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.
