name: go-memory-optimization
description: This skill should be used when optimizing Go code for memory efficiency, reducing GC pressure, implementing object pooling, analyzing escape behavior, choosing between fixed-size arrays and slices, designing worker pools, or profiling memory allocations. Provides comprehensive knowledge of Go's memory model, stack vs heap allocation, sync.Pool patterns, goroutine reuse, and GC tuning.

# Go Memory Optimization
## Overview
This skill provides guidance on optimizing Go programs for memory efficiency and reduced garbage collection overhead. Topics include stack allocation semantics, fixed-size types, escape analysis, object pooling, goroutine management, and GC tuning.
## Core Principles
### The Allocation Hierarchy
Prefer allocations in this order (fastest to slowest):
1. **Stack allocation** - Zero GC cost, automatic cleanup on function return
2. **Pooled objects** - Amortized allocation cost via sync.Pool
3. **Pre-allocated buffers** - Single allocation, reused across operations
4. **Heap allocation** - GC-managed, use when lifetime exceeds function scope
### When Optimization Matters
Focus memory optimization efforts on:
- Hot paths executed thousands/millions of times per second
- Large objects (>32KB) that stress the GC
- Long-running services where GC pauses affect latency
- Memory-constrained environments
Avoid premature optimization. Profile first with `go tool pprof` to identify actual bottlenecks.
## Fixed-Size Types vs Slices
### Stack Allocation with Arrays
Arrays with known compile-time size can be stack-allocated, avoiding heap entirely:
```go
// HEAP: slice header + backing array escape to heap
func processSlice() []byte {
data := make([]byte, 32)
// ... use data
return data // escapes
}
// STACK: fixed array stays on stack if doesn't escape
func processArray() {
var data [32]byte // stack-allocated
// ... use data
} // automatically cleaned up
```
### Fixed-Size Binary Types Pattern
Define types with explicit sizes for protocol fields, cryptographic values, and identifiers:
```go
// Binary types enforce length and enable stack allocation
type EventID [32]byte // SHA256 hash
type Pubkey [32]byte // Schnorr public key
type Signature [64]byte // Schnorr signature
// Methods operate on value receivers when size permits
func (id EventID) Hex() string {
return hex.EncodeToString(id[:])
}
func (id EventID) IsZero() bool {
return id == EventID{} // efficient zero-value comparison
}
```
### Size Thresholds
| Size | Recommendation |
|------|----------------|
| ≤64 bytes | Pass by value, stack-friendly |
| 65-128 bytes | Consider context; value for read-only, pointer for mutation |
| >128 bytes | Pass by pointer to avoid copy overhead |
### Array to Slice Conversion
Convert fixed arrays to slices only at API boundaries:
```go
type Hash [32]byte
func (h Hash) Bytes() []byte {
return h[:] // creates slice header, array stays on stack if h does
}
// Prefer methods that accept arrays directly
func VerifySignature(pubkey Pubkey, msg []byte, sig Signature) bool {
// pubkey and sig are stack-allocated in caller
}
```
## Escape Analysis
### Understanding Escape
Variables "escape" to the heap when the compiler cannot prove their lifetime is bounded by the stack frame. Check escape behavior with:
```bash
go build -gcflags="-m -m" ./...
```
### Common Escape Causes
```go
// 1. Returning pointers to local variables
func escapes() *int {
x := 42
return &x // x escapes
}
// 2. Storing in interface{}
func escapes(x int) interface{} {
return x // x escapes (boxed)
}
// 3. Closures capturing by reference
func escapes() func() int {
x := 42
return func() int { return x } // x escapes
}
// 4. Slice/map with unknown capacity
func escapes(n int) []byte {
return make([]byte, n) // escapes (size unknown at compile time)
}
// 5. Sending pointers to channels
func escapes(ch chan *int) {
x := 42
ch <- &x // x escapes
}
```
### Preventing Escape
```go
// 1. Accept pointers, don't return them
func noEscape(result *[32]byte) {
// caller owns memory, function fills it
copy(result[:], computeHash())
}
// 2. Use fixed-size arrays
func noEscape() {
var buf [1024]byte // known size, stack-allocated
process(buf[:])
}
// 3. Preallocate with known capacity
func noEscape() {
buf := make([]byte, 0, 1024) // may stay on stack
// ... append up to 1024 bytes
}
// 4. Avoid interface{} on hot paths
func noEscape(x int) int {
return x * 2 // no boxing
}
```
## sync.Pool Usage
### Basic Pattern
```go
var bufferPool = sync.Pool{
New: func() interface{} {
return make([]byte, 0, 4096)
},
}
func processRequest(data []byte) {
buf := bufferPool.Get().([]byte)
buf = buf[:0] // reset length, keep capacity
defer bufferPool.Put(buf)
// use buf...
}
```
### Typed Pool Wrapper
```go
type BufferPool struct {
pool sync.Pool
size int
}
func NewBufferPool(size int) *BufferPool {
return &BufferPool{
pool: sync.Pool{
New: func() interface{} {
b := make([]byte, size)
return &b
},
},
size: size,
}
}
func (p *BufferPool) Get() *[]byte {
return p.pool.Get().(*[]byte)
}
func (p *BufferPool) Put(b *[]byte) {
if b == nil || cap(*b) < p.size {
return // don't pool undersized buffers
}
*b = (*b)[:p.size] // reset to full size
p.pool.Put(b)
}
```
### Pool Anti-Patterns
```go
// BAD: Pool of pointers to small values (overhead exceeds benefit)
var intPool = sync.Pool{New: func() interface{} { return new(int) }}
// BAD: Not resetting state before Put
bufPool.Put(buf) // may contain sensitive data
// BAD: Pooling objects with goroutine-local state
var connPool = sync.Pool{...} // connections are stateful
// BAD: Assuming pooled objects persist (GC clears pools)
obj := pool.Get()
// ... long delay
pool.Put(obj) // obj may have been GC'd during delay
```
### When to Use sync.Pool
| Use Case | Pool? | Reason |
|----------|-------|--------|
| Buffers in HTTP handlers | Yes | High allocation rate, short lifetime |
| Encoder/decoder state | Yes | Expensive to initialize |
| Small values (<64 bytes) | No | Pointer overhead exceeds benefit |
| Long-lived objects | No | Pools are for short-lived reuse |
| Objects with cleanup needs | No | Pool provides no finalization |
## Goroutine Pooling
### Worker Pool Pattern
```go
type WorkerPool struct {
jobs chan func()
workers int
wg sync.WaitGroup
}
func NewWorkerPool(workers, queueSize int) *WorkerPool {
p := &WorkerPool{
jobs: make(chan func(), queueSize),
workers: workers,
}
p.wg.Add(workers)
for i := 0; i < workers; i++ {
go p.worker()
}
return p
}
func (p *WorkerPool) worker() {
defer p.wg.Done()
for job := range p.jobs {
job()
}
}
func (p *WorkerPool) Submit(job func()) {
p.jobs <- job
}
func (p *WorkerPool) Shutdown() {
close(p.jobs)
p.wg.Wait()
}
```
### Bounded Concurrency with Semaphore
```go
type Semaphore struct {
sem chan struct{}
}
func NewSemaphore(n int) *Semaphore {
return &Semaphore{sem: make(chan struct{}, n)}
}
func (s *Semaphore) Acquire() { s.sem <- struct{}{} }
func (s *Semaphore) Release() { <-s.sem }
// Usage
sem := NewSemaphore(runtime.GOMAXPROCS(0))
for _, item := range items {
sem.Acquire()
go func(it Item) {
defer sem.Release()
process(it)
}(item)
}
```
### Goroutine Reuse Benefits
| Metric | Spawn per request | Worker pool |
|--------|-------------------|-------------|
| Goroutine creation | O(n) | O(workers) |
| Stack allocation | 2KB × n | 2KB × workers |
| Scheduler overhead | Higher | Lower |
| GC pressure | Higher | Lower |
## Reducing GC Pressure
### Allocation Reduction Strategies
```go
// 1. Reuse buffers across iterations
buf := make([]byte, 0, 4096)
for _, item := range items {
buf = buf[:0] // reset without reallocation
buf = processItem(buf, item)
}
// 2. Preallocate slices with known length
result := make([]Item, 0, len(input)) // avoid append reallocations
for _, in := range input {
result = append(result, transform(in))
}
// 3. Struct embedding instead of pointer fields
type Event struct {
ID [32]byte // embedded, not *[32]byte
Pubkey [32]byte // single allocation for entire struct
Signature [64]byte
Content string // only string data on heap
}
// 4. String interning for repeated values
var kindStrings = map[int]string{
0: "set_metadata",
1: "text_note",
// ...
}
```
### GC Tuning
```go
import "runtime/debug"
func init() {
// GOGC: target heap growth percentage (default 100)
// Lower = more frequent GC, less memory
// Higher = less frequent GC, more memory
debug.SetGCPercent(50) // GC when heap grows 50%
// GOMEMLIMIT: soft memory limit (Go 1.19+)
// GC becomes more aggressive as limit approaches
debug.SetMemoryLimit(512 << 20) // 512MB limit
}
```
Environment variables:
```bash
GOGC=50 # More aggressive GC
GOMEMLIMIT=512MiB # Soft memory limit
GODEBUG=gctrace=1 # GC trace output
```
### Arena Allocation (Go 1.20+, experimental)
```go
//go:build goexperiment.arenas
import "arena"
func processLargeDataset(data []byte) Result {
a := arena.NewArena()
defer a.Free() // bulk free all allocations
// All allocations from arena are freed together
items := arena.MakeSlice[Item](a, 0, 1000)
// ... process
// Copy result out before Free
return copyResult(result)
}
```
## Memory Profiling
### Heap Profile
```go
import "runtime/pprof"
func captureHeapProfile() {
f, _ := os.Create("heap.prof")
defer f.Close()
runtime.GC() // get accurate picture
pprof.WriteHeapProfile(f)
}
```
```bash
go tool pprof -http=:8080 heap.prof
go tool pprof -alloc_space heap.prof # total allocations
go tool pprof -inuse_space heap.prof # current usage
```
### Allocation Benchmarks
```go
func BenchmarkAllocation(b *testing.B) {
b.ReportAllocs()
for i := 0; i < b.N; i++ {
result := processData(input)
_ = result
}
}
```
Output interpretation:
```
BenchmarkAllocation-8 1000000 1234 ns/op 256 B/op 3 allocs/op
↑ ↑
bytes/op allocations/op
```
### Live Memory Monitoring
```go
func printMemStats() {
var m runtime.MemStats
runtime.ReadMemStats(&m)
fmt.Printf("Alloc: %d MB\n", m.Alloc/1024/1024)
fmt.Printf("TotalAlloc: %d MB\n", m.TotalAlloc/1024/1024)
fmt.Printf("Sys: %d MB\n", m.Sys/1024/1024)
fmt.Printf("NumGC: %d\n", m.NumGC)
fmt.Printf("GCPause: %v\n", time.Duration(m.PauseNs[(m.NumGC+255)%256]))
}
```

# Go Memory Optimization Patterns
Detailed code examples and patterns for memory-efficient Go programming.
## Buffer Pool Implementations
### Tiered Buffer Pool
For workloads with varying buffer sizes:
```go
type TieredPool struct {
small sync.Pool // 1KB
medium sync.Pool // 16KB
large sync.Pool // 256KB
}
func NewTieredPool() *TieredPool {
return &TieredPool{
small: sync.Pool{New: func() interface{} { return make([]byte, 1024) }},
medium: sync.Pool{New: func() interface{} { return make([]byte, 16384) }},
large: sync.Pool{New: func() interface{} { return make([]byte, 262144) }},
}
}
func (p *TieredPool) Get(size int) []byte {
switch {
case size <= 1024:
return p.small.Get().([]byte)[:size]
case size <= 16384:
return p.medium.Get().([]byte)[:size]
case size <= 262144:
return p.large.Get().([]byte)[:size]
default:
return make([]byte, size) // too large for pool
}
}
func (p *TieredPool) Put(b []byte) {
switch cap(b) {
case 1024:
p.small.Put(b[:cap(b)])
case 16384:
p.medium.Put(b[:cap(b)])
case 262144:
p.large.Put(b[:cap(b)])
}
// Non-standard sizes are not pooled
}
```
### bytes.Buffer Pool
```go
var bufferPool = sync.Pool{
New: func() interface{} {
return new(bytes.Buffer)
},
}
func GetBuffer() *bytes.Buffer {
return bufferPool.Get().(*bytes.Buffer)
}
func PutBuffer(b *bytes.Buffer) {
b.Reset()
bufferPool.Put(b)
}
// Usage
func processData(data []byte) string {
buf := GetBuffer()
defer PutBuffer(buf)
buf.WriteString("prefix:")
buf.Write(data)
buf.WriteString(":suffix")
return buf.String() // allocates new string
}
```
## Zero-Allocation JSON Encoding
### Pre-allocated Encoder
```go
type JSONEncoder struct {
buf []byte
scratch [64]byte // for number formatting
}
func (e *JSONEncoder) Reset() {
e.buf = e.buf[:0]
}
func (e *JSONEncoder) Bytes() []byte {
return e.buf
}
func (e *JSONEncoder) WriteString(s string) {
e.buf = append(e.buf, '"')
for i := 0; i < len(s); i++ {
c := s[i]
switch c {
case '"':
e.buf = append(e.buf, '\\', '"')
case '\\':
e.buf = append(e.buf, '\\', '\\')
case '\n':
e.buf = append(e.buf, '\\', 'n')
case '\r':
e.buf = append(e.buf, '\\', 'r')
case '\t':
e.buf = append(e.buf, '\\', 't')
default:
if c < 0x20 {
e.buf = append(e.buf, '\\', 'u', '0', '0',
hexDigits[c>>4], hexDigits[c&0xf])
} else {
e.buf = append(e.buf, c)
}
}
}
e.buf = append(e.buf, '"')
}
func (e *JSONEncoder) WriteInt(n int64) {
e.buf = strconv.AppendInt(e.buf, n, 10)
}
func (e *JSONEncoder) WriteHex(b []byte) {
e.buf = append(e.buf, '"')
for _, v := range b {
e.buf = append(e.buf, hexDigits[v>>4], hexDigits[v&0xf])
}
e.buf = append(e.buf, '"')
}
var hexDigits = [16]byte{'0', '1', '2', '3', '4', '5', '6', '7',
'8', '9', 'a', 'b', 'c', 'd', 'e', 'f'}
```
### Append-Based Encoding
```go
// AppendJSON appends JSON representation to dst, returning extended slice
func (ev *Event) AppendJSON(dst []byte) []byte {
dst = append(dst, `{"id":"`...)
dst = appendHex(dst, ev.ID[:])
dst = append(dst, `","pubkey":"`...)
dst = appendHex(dst, ev.Pubkey[:])
dst = append(dst, `","created_at":`...)
dst = strconv.AppendInt(dst, ev.CreatedAt, 10)
dst = append(dst, `,"kind":`...)
dst = strconv.AppendInt(dst, int64(ev.Kind), 10)
dst = append(dst, `,"content":`...)
dst = appendJSONString(dst, ev.Content)
dst = append(dst, '}')
return dst
}
// Usage with pre-allocated buffer
func encodeEvents(events []Event) []byte {
// Estimate size: ~500 bytes per event
buf := make([]byte, 0, len(events)*500)
buf = append(buf, '[')
for i, ev := range events {
if i > 0 {
buf = append(buf, ',')
}
buf = ev.AppendJSON(buf)
}
buf = append(buf, ']')
return buf
}
```
## Memory-Efficient String Building
### strings.Builder with Preallocation
```go
func buildQuery(parts []string) string {
// Calculate total length
total := len(parts) - 1 // for separators
for _, p := range parts {
total += len(p)
}
var b strings.Builder
b.Grow(total) // single allocation
for i, p := range parts {
if i > 0 {
b.WriteByte(',')
}
b.WriteString(p)
}
return b.String()
}
```
### Avoiding String Concatenation
```go
// BAD: O(n^2) allocations
func buildPath(parts []string) string {
result := ""
for _, p := range parts {
result += "/" + p // new allocation each iteration
}
return result
}
// GOOD: O(n) with single allocation
func buildPath(parts []string) string {
if len(parts) == 0 {
return ""
}
n := len(parts) // for slashes
for _, p := range parts {
n += len(p)
}
b := make([]byte, 0, n)
for _, p := range parts {
b = append(b, '/')
b = append(b, p...)
}
return string(b)
}
```
### Unsafe String/Byte Conversion
```go
import "unsafe"
// Zero-allocation string to []byte (read-only!)
func unsafeBytes(s string) []byte {
return unsafe.Slice(unsafe.StringData(s), len(s))
}
// Zero-allocation []byte to string (b must not be modified!)
func unsafeString(b []byte) string {
return unsafe.String(unsafe.SliceData(b), len(b))
}
// Use when:
// 1. Converting string for read-only operations (hashing, comparison)
// 2. Returning []byte from buffer that won't be modified
// 3. Performance-critical paths with careful ownership management
```
## Slice Capacity Management
### Append Growth Patterns
```go
// Slice growth: 0 -> 1 -> 2 -> 4 -> 8 -> 16 -> 32 -> 64 -> ...
// After 1024: grows by 25% each time
// BAD: Unknown final size causes multiple reallocations
func collectItems() []Item {
var items []Item
for item := range source {
items = append(items, item) // may reallocate multiple times
}
return items
}
// GOOD: Preallocate when size is known
func collectItems(n int) []Item {
items := make([]Item, 0, n)
for item := range source {
items = append(items, item)
}
return items
}
// GOOD: Use slice header trick for uncertain sizes
func collectItems() []Item {
items := make([]Item, 0, 32) // reasonable initial capacity
for item := range source {
items = append(items, item)
}
// Trim excess capacity if items will be long-lived
return items[:len(items):len(items)]
}
```
### Slice Recycling
```go
// Reuse slice backing array
func processInBatches(items []Item, batchSize int) {
batch := make([]Item, 0, batchSize)
for i, item := range items {
batch = append(batch, item)
if len(batch) == batchSize || i == len(items)-1 {
processBatch(batch)
batch = batch[:0] // reset length, keep capacity
}
}
}
```
### Preventing Slice Memory Leaks
```go
// BAD: Subslice keeps entire backing array alive
func getFirst10(data []byte) []byte {
return data[:10] // entire data array stays in memory
}
// GOOD: Copy to release original array
func getFirst10(data []byte) []byte {
result := make([]byte, 10)
copy(result, data[:10])
return result
}
// Alternative: explicit capacity limit
func getFirst10(data []byte) []byte {
return data[:10:10] // cap=10, can't accidentally grow into original
}
```
## Struct Layout Optimization
### Field Ordering for Alignment
```go
// BAD: 32 bytes due to padding
type BadLayout struct {
a bool // 1 byte + 7 padding
b int64 // 8 bytes
c bool // 1 byte + 7 padding
d int64 // 8 bytes
}
// GOOD: 24 bytes with optimal ordering
type GoodLayout struct {
b int64 // 8 bytes
d int64 // 8 bytes
a bool // 1 byte
c bool // 1 byte + 6 padding
}
// Rule: Order fields from largest to smallest alignment
```
### Checking Struct Size
```go
func init() {
// Compile-time size assertions
var _ [24]byte = [unsafe.Sizeof(GoodLayout{})]byte{}
// Or runtime check
if unsafe.Sizeof(Event{}) > 256 {
panic("Event struct too large")
}
}
```
### Cache-Line Optimization
```go
const CacheLineSize = 64
// Pad struct to prevent false sharing in concurrent access
type PaddedCounter struct {
value uint64
_ [CacheLineSize - 8]byte // padding
}
type Counters struct {
reads PaddedCounter
writes PaddedCounter
// Each counter on separate cache line
}
```
## Object Reuse Patterns
### Reset Methods
```go
type Request struct {
Method string
Path string
Headers map[string]string
Body []byte
}
func (r *Request) Reset() {
r.Method = ""
r.Path = ""
// Reuse map, just clear entries
for k := range r.Headers {
delete(r.Headers, k)
}
r.Body = r.Body[:0]
}
var requestPool = sync.Pool{
New: func() interface{} {
return &Request{
Headers: make(map[string]string, 8),
Body: make([]byte, 0, 1024),
}
},
}
```
### Flyweight Pattern
```go
// Share immutable parts across many instances
type Event struct {
kind *Kind // shared, immutable
content string
}
type Kind struct {
ID int
Name string
Description string
}
var kindRegistry = map[int]*Kind{
0: {0, "set_metadata", "User metadata"},
1: {1, "text_note", "Text note"},
// ... pre-allocated, shared across all events
}
func NewEvent(kindID int, content string) Event {
return Event{
kind: kindRegistry[kindID], // no allocation
content: content,
}
}
```
## Channel Patterns for Memory Efficiency
### Buffered Channels as Object Pools
```go
type SimplePool struct {
pool chan *Buffer
}
func NewSimplePool(size int) *SimplePool {
p := &SimplePool{pool: make(chan *Buffer, size)}
for i := 0; i < size; i++ {
p.pool <- NewBuffer()
}
return p
}
func (p *SimplePool) Get() *Buffer {
select {
case b := <-p.pool:
return b
default:
return NewBuffer() // pool empty, allocate new
}
}
func (p *SimplePool) Put(b *Buffer) {
select {
case p.pool <- b:
default:
// pool full, let GC collect
}
}
```
### Batch Processing Channels
```go
// Reduce channel overhead by batching
func batchProcessor(input <-chan Item, batchSize int) <-chan []Item {
output := make(chan []Item)
go func() {
defer close(output)
batch := make([]Item, 0, batchSize)
for item := range input {
batch = append(batch, item)
if len(batch) == batchSize {
output <- batch
batch = make([]Item, 0, batchSize)
}
}
if len(batch) > 0 {
output <- batch
}
}()
return output
}
```
## Advanced Techniques
### Manual Memory Management with mmap
```go
import "golang.org/x/sys/unix"
// Allocate memory outside Go heap
func allocateMmap(size int) ([]byte, error) {
data, err := unix.Mmap(-1, 0, size,
unix.PROT_READ|unix.PROT_WRITE,
unix.MAP_ANON|unix.MAP_PRIVATE)
return data, err
}
func freeMmap(data []byte) error {
return unix.Munmap(data)
}
```
### Inline Arrays in Structs
```go
// Small-size optimization: inline for small, pointer for large

### 5. Add Domain-Specific Error Types
**Problem:** Errors are strings or generic types, making error handling imprecise.
**Problem:** Errors are strings or generic types.
**Solution:** Create typed domain errors.
**Solution:** Create typed domain errors in `pkg/interfaces/neterr/` pattern:
```go
// pkg/domain/errors/errors.go
package errors
type DomainError struct {
Code string
Message string
Cause error
}
var (
ErrEventInvalid = &DomainError{Code: "EVENT_INVALID"}
ErrEventBlocked = &DomainError{Code: "EVENT_BLOCKED"}
ErrAuthRequired = &DomainError{Code: "AUTH_REQUIRED"}
ErrQuotaExceeded = &DomainError{Code: "QUOTA_EXCEEDED"}
ErrInviteCodeInvalid = &DomainError{Code: "INVITE_INVALID"}
ErrInviteCodeExpired = &DomainError{Code: "INVITE_EXPIRED"}
ErrInviteCodeUsed = &DomainError{Code: "INVITE_USED"}
ErrBlobTooLarge = &DomainError{Code: "BLOB_TOO_LARGE"}
)
```
**Benefits:**
- Precise error handling in handlers
- Better error messages to clients
- Easier testing
### 6. Enforce Value Object Immutability - **ADDRESSED**
### 6. Enforce Value Object Immutability
**Problem:** Value objects use mutable slices.
**Solution:** Return copies from accessors.
The `EventRef` type now provides an immutable alternative:
```go
// pkg/interfaces/store/store_interface.go
type IdPkTs struct {
id []byte // unexported
pub []byte // unexported
// pkg/interfaces/store/store_interface.go:99-153
type EventRef struct {
id ntypes.EventID // unexported
pub ntypes.Pubkey // unexported
ts int64
ser uint64
}
func NewIdPkTs(id, pub []byte, ts int64, ser uint64) *IdPkTs {
return &IdPkTs{
id: append([]byte(nil), id...), // Copy
pub: append([]byte(nil), pub...), // Copy
ts: ts,
ser: ser,
}
}
func (i *IdPkTs) ID() []byte { return append([]byte(nil), i.id...) }
func (i *IdPkTs) Pub() []byte { return append([]byte(nil), i.pub...) }
func (i *IdPkTs) Ts() int64 { return i.ts }
func (i *IdPkTs) Ser() uint64 { return i.ser }
func (r EventRef) ID() ntypes.EventID { return r.id } // Returns copy
func (r EventRef) IDHex() string { return r.id.Hex() }
func (i *IdPkTs) ToEventRef() EventRef // Migration path
```
### 7. Document Context Map
### 7. Document Context Map - **THIS DOCUMENT**
**Problem:** Context relationships are implicit.
**Solution:** Add a `CONTEXT_MAP.md` documenting boundaries and integration patterns.
The diagram in the [Context Map](#context-map) section above should be maintained as living documentation.
The context map is now documented in this file with integration patterns.

# ORLY Relay Memory Optimization Analysis
This document analyzes ORLY's current memory optimization patterns against Go best practices for high-performance systems. The analysis covers buffer management, caching strategies, allocation patterns, and identifies optimization opportunities.
## Executive Summary
ORLY implements several sophisticated memory optimization strategies:
- **Compact event storage** achieving ~87% space savings via serial references
- **Two-level caching** for serial lookups and query results
- **ZSTD compression** for query cache with LRU eviction
- **Atomic operations** for lock-free statistics tracking
- **Pre-allocation patterns** for slice capacity management
However, several opportunities exist to further reduce GC pressure:
- Implement `sync.Pool` for frequently allocated buffers
- Use fixed-size arrays for cryptographic values
- Pool `bytes.Buffer` instances in hot paths
- Optimize escape behavior in serialization code
---
## Current Memory Patterns
### 1. Compact Event Storage
**Location**: `pkg/database/compact_event.go`
ORLY's most significant memory optimization is the compact binary format for event storage:
```
Original event: 32 (ID) + 32 (pubkey) + 32*4 (tags) = 192+ bytes
Compact format: 5 (pubkey serial) + 5*4 (tag serials) = 25 bytes
Savings: ~87% compression per event
```
**Key techniques:**
- 5-byte serial references replace 32-byte IDs/pubkeys
- Varint encoding for variable-length integers (CreatedAt, tag counts)
- Type flags for efficient deserialization
- Separate `SerialEventId` index for ID reconstruction
**Assessment**: Excellent storage optimization. This dramatically reduces database size and I/O costs.
### 2. Serial Cache System
**Location**: `pkg/database/serial_cache.go`
Two-way lookup cache for serial ↔ ID/pubkey mappings:
```go
type SerialCache struct {
pubkeyBySerial map[uint64][]byte // For decoding
serialByPubkeyHash map[string]uint64 // For encoding
eventIdBySerial map[uint64][]byte // For decoding
serialByEventIdHash map[string]uint64 // For encoding
}
```
**Memory footprint:**
- Pubkey cache: 100k entries × 32 bytes ≈ 3.2MB
- Event ID cache: 500k entries × 32 bytes ≈ 16MB
- Total: ~19-20MB overhead
**Strengths:**
- Fine-grained `RWMutex` locking per direction/type
- Configurable cache limits
- Defensive copying prevents external mutations
**Improvement opportunity:** The eviction strategy (clear 50% when full) is simple but not LRU. Consider ring buffers or generational caching for better hit rates.
### 3. Query Cache with ZSTD Compression
**Location**: `pkg/database/querycache/event_cache.go`
```go
type EventCache struct {
entries map[string]*EventCacheEntry
lruList *list.List
encoder *zstd.Encoder // Reused encoder (level 9)
decoder *zstd.Decoder // Reused decoder
maxSize int64 // Default 512MB compressed
}
```
**Strengths:**
- ZSTD level 9 compression (best ratio)
- Encoder/decoder reuse avoids repeated initialization
- LRU eviction with proper size tracking
- Background cleanup of expired entries
- Tracks compression ratio with exponential moving average
**Memory pattern:** Stores compressed data in cache, decompresses on-demand. This trades CPU for memory.
### 4. Buffer Allocation Patterns
**Current approach:** Uses `new(bytes.Buffer)` throughout serialization code:
```go
// pkg/database/save-event.go, compact_event.go, serial_cache.go
buf := new(bytes.Buffer)
// ... encode data
return buf.Bytes()
```
**Assessment:** Each call allocates a new buffer on the heap. For high-throughput scenarios (thousands of events/second), this creates significant GC pressure.
---
## Optimization Opportunities
### 1. Implement sync.Pool for Buffer Reuse
**Priority: High**
Currently, ORLY creates new `bytes.Buffer` instances for every serialization operation. A buffer pool would amortize allocation costs:
```go
// Recommended implementation
var bufferPool = sync.Pool{
New: func() interface{} {
return bytes.NewBuffer(make([]byte, 0, 4096))
},
}
func getBuffer() *bytes.Buffer {
return bufferPool.Get().(*bytes.Buffer)
}
func putBuffer(buf *bytes.Buffer) {
buf.Reset()
bufferPool.Put(buf)
}
```
**Impact areas:**
- `pkg/database/compact_event.go` - MarshalCompactEvent, encodeCompactTag
- `pkg/database/save-event.go` - index key generation
- `pkg/database/serial_cache.go` - GetEventIdBySerial, StoreEventIdSerial
**Expected benefit:** 50-80% reduction in buffer allocations on hot paths.
### 2. Fixed-Size Array Types for Cryptographic Values
**Priority: Medium**
The external nostr library uses `[]byte` slices for IDs, pubkeys, and signatures. However, these are always fixed sizes:
| Type | Size | Current | Recommended |
|------|------|---------|-------------|
| Event ID | 32 bytes | `[]byte` | `[32]byte` |
| Pubkey | 32 bytes | `[]byte` | `[32]byte` |
| Signature | 64 bytes | `[]byte` | `[64]byte` |
Internal types like `Uint40` already follow this pattern but use struct wrapping:
```go
// Current (pkg/database/indexes/types/uint40.go)
type Uint40 struct{ value uint64 }
// Already efficient - no slice allocation
```
For cryptographic values, consider wrapper types:
```go
type EventID [32]byte
type Pubkey [32]byte
type Signature [64]byte
func (id EventID) IsZero() bool { return id == EventID{} }
func (id EventID) Hex() string { return hex.Enc(id[:]) }
```
**Benefit:** Stack allocation for local variables, zero-value comparison efficiency.
### 3. Pre-allocated Slice Patterns
**Current usage is good:**
```go
// pkg/database/save-event.go:51-54
sers = make(types.Uint40s, 0, len(idxs)*100) // Estimate 100 serials per index
// pkg/database/compact_event.go:283
ev.Tags = tag.NewSWithCap(int(nTags)) // Pre-allocate tag slice
```
**Improvement:** Apply consistently to:
- `Uint40s.Union/Intersection/Difference` methods (currently use `append` without capacity hints)
- Query result accumulation in `query-events.go`
### 4. Escape Analysis Optimization
**Priority: Medium**
Several patterns cause unnecessary heap escapes. Check with:
```bash
go build -gcflags="-m -m" ./pkg/database/...
```
**Common escape causes in codebase:**
```go
// compact_event.go:224 - Small slice escapes
buf := make([]byte, 5) // Could be [5]byte on stack
// compact_event.go:335 - Single-byte slice escapes
typeBuf := make([]byte, 1) // Could be var typeBuf [1]byte
```
**Fix:**
```go
func readUint40(r io.Reader) (value uint64, err error) {
var buf [5]byte // Stack-allocated
if _, err = io.ReadFull(r, buf[:]); err != nil {
return 0, err
}
// ...
}
```
### 5. Atomic Bytes Wrapper Optimization
**Location**: `pkg/utils/atomic/bytes.go`
Current implementation copies on both Load and Store:
```go
func (x *Bytes) Load() (b []byte) {
vb := x.v.Load().([]byte)
b = make([]byte, len(vb)) // Allocation on every Load
copy(b, vb)
return
}
```
This is safe but expensive for high-frequency access. Consider:
- Read-copy-update (RCU) pattern for read-heavy workloads
- `sync.RWMutex` with direct access for controlled use cases
### 6. Goroutine Management
**Current patterns:**
- Worker goroutines for message processing (`app/listener.go`)
- Background cleanup goroutines (`querycache/event_cache.go`)
- Pinger goroutines per connection (`app/handle-websocket.go`)
**Assessment:** Good use of bounded channels and `sync.WaitGroup` for lifecycle management.
**Improvement:** Consider a worker pool for subscription handlers to limit peak goroutine count:
```go
type WorkerPool struct {
jobs chan func()
workers int
wg sync.WaitGroup
}
```
---
## Memory Budget Analysis
### Runtime Memory Breakdown
| Component | Estimated Size | Notes |
|-----------|---------------|-------|
| Serial Cache (pubkeys) | 3.2 MB | 100k × 32 bytes |
| Serial Cache (event IDs) | 16 MB | 500k × 32 bytes |
| Query Cache | 512 MB | Configurable, compressed |
| Per-connection state | ~10 KB | Channels, buffers, maps |
| Badger DB caches | Variable | Controlled by Badger config |
### GC Tuning Recommendations
For a relay handling 1000+ events/second:
```go
// main.go or init
import "runtime/debug"
func init() {
// More aggressive GC to limit heap growth
debug.SetGCPercent(50) // GC at 50% heap growth (default 100)
// Set soft memory limit based on available RAM
debug.SetMemoryLimit(2 << 30) // 2GB limit
}
```
Or via environment:
```bash
GOGC=50 GOMEMLIMIT=2GiB ./orly
```
---
## Profiling Commands
### Heap Profile
```bash
# Enable pprof (already supported)
ORLY_PPROF_HTTP=true ./orly
# Capture heap profile
go tool pprof http://localhost:6060/debug/pprof/heap
# Analyze allocations
go tool pprof -alloc_space heap.prof
go tool pprof -inuse_space heap.prof
```
### Escape Analysis
```bash
# Check which variables escape to heap
go build -gcflags="-m -m" ./pkg/database/... 2>&1 | grep "escapes to heap"
```
### Allocation Benchmarks
Add to existing benchmarks:
```go
func BenchmarkCompactMarshal(b *testing.B) {
b.ReportAllocs()
ev := createTestEvent()
resolver := &testResolver{}
b.ResetTimer()
for i := 0; i < b.N; i++ {
data, _ := MarshalCompactEvent(ev, resolver)
_ = data
}
}
```
---
## Implementation Priority
1. **High Priority (Immediate Impact)**
- Implement `sync.Pool` for `bytes.Buffer` in serialization paths
- Replace small `make([]byte, n)` with fixed arrays in decode functions
2. **Medium Priority (Significant Improvement)**
- Add pre-allocation hints to set operation methods
- Optimize escape behavior in compact event encoding
- Consider worker pool for subscription handlers
3. **Low Priority (Refinement)**
- LRU-based serial cache eviction
- Fixed-size types for cryptographic values (requires nostr library changes)
- RCU pattern for atomic bytes in high-frequency paths
---
## Conclusion
ORLY demonstrates thoughtful memory optimization in its storage layer, particularly the compact event format achieving 87% space savings. The dual-cache architecture (serial cache + query cache) balances memory usage with lookup performance.
The primary opportunity for improvement is in the serialization hot path, where buffer pooling could significantly reduce GC pressure. The recommended `sync.Pool` implementation would have immediate benefits for high-throughput deployments without requiring architectural changes.
Secondary improvements around escape analysis and fixed-size types would provide incremental gains and should be prioritized based on profiling data from production workloads.
