## Performance Summary
### Publishing Performance
| Metric | Best Result | Test Configuration |
|--------|-------------|-------------------|
| **Peak Event Rate** | 21,118.66 events/sec | 50 concurrent publishers, 512-byte events |
| **Peak Bandwidth** | 198.28 MB/sec | 10 concurrent publishers, 10KB events |
| **Optimal Balance** | 16,714.00 events/sec @ 128.38 MB/sec | 10 concurrent publishers, 2KB events |
### Query Performance
| Query Type | Avg Rate | Notes |
|------------|----------|--------|
| **Light Load** | 16.35 queries/sec | 50 queries after 1K events |
| **Medium Load** | 11.21 queries/sec | 100 queries after 10K events |
| **Heavy Load** | 5.53 queries/sec | 200 queries after 50K events |
| **Sustained** | 6.72 queries/sec | 500 continuous queries |
## Key Findings
1. **Optimal Concurrency**: The relay performs best with 10-50 concurrent publishers, achieving rates of 16,000-21,000 events/second.
2. **Event Size Impact**:
- Smaller events (512B-2KB) achieve higher event rates
- Larger events (10KB) achieve higher bandwidth utilization but lower event rates
3. **Query Performance**: Query performance varies with database size:
- Fresh database: ~16 queries/second
- After 50K events: ~6 queries/second
4. **Scalability**: The relay maintains consistent performance up to 50 concurrent connections and can sustain 21,000+ events/second under optimal conditions.
## Query Filter Distribution
The benchmark tested 5 different query patterns in rotation:
1. Query by kind (20%)
2. Query by time range (20%)
3. Query by tag (20%)
4. Query by author (20%)
5. Complex queries with multiple conditions (20%)
All query types showed similar performance characteristics, indicating well-balanced indexing.

# Orly Relay Benchmark Tool # Nostr Relay Benchmark Suite
A performance benchmarking tool for Nostr relays that tests both event ingestion speed and query performance. A comprehensive performance benchmarking suite for Nostr relay implementations, featuring event publishing tests, query profiling, load simulation, and timing instrumentation.
## Quick Start (Simple Version)
The repository includes a simple standalone benchmark tool that doesn't require the full Orly dependencies:
```bash
# Build the simple benchmark
go build -o benchmark-simple ./benchmark_simple.go
# Run with default settings
./benchmark-simple
# Or use the convenience script
chmod +x run_benchmark.sh
./run_benchmark.sh --relay ws://localhost:7447 --events 10000
```
## Features ## Features
- **Event Publishing Benchmark**: Tests how fast a relay can accept and store events - **Multi-relay comparison benchmarks** - Compare Khatru, Strfry, Relayer, and Orly
- **Query Performance Benchmark**: Tests various filter types and query speeds - **Publishing performance testing** - Measure event ingestion rates and bandwidth
- **Concurrent Publishing**: Supports multiple concurrent publishers to stress test the relay - **Query profiling** - Test various filter patterns and query speeds
- **Detailed Metrics**: Reports events/second, bandwidth usage, and query performance - **Load pattern simulation** - Constant, spike, burst, sine, and ramp patterns
- **Timing instrumentation** - Track full event lifecycle and identify bottlenecks
- **Concurrent stress testing** - Multiple publishers with connection pooling
- **Production-grade event generation** - Proper secp256k1 signatures and UTF-8 content
- **Comparative reporting** - Markdown, JSON, and CSV format reports

## Relay Setup
First run `./setup_relays.sh` to build all relay binaries, then start individual relays:
### Khatru (SQLite)
```bash
cd /tmp/relay-benchmark/khatru/examples/basic-sqlite3
./khatru-relay
```
### Strfry (LMDB)
```bash
cd /tmp/relay-benchmark/strfry
./strfry --config strfry.conf relay
```
### Relayer (PostgreSQL)
```bash
# Start PostgreSQL
docker run -d --name relay-postgres -e POSTGRES_PASSWORD=postgres \
-e POSTGRES_DB=nostr -p 5433:5432 postgres:15-alpine
# Run relayer
cd /tmp/relay-benchmark/relayer/examples/basic
POSTGRESQL_DATABASE="postgres://postgres:postgres@localhost:5433/nostr?sslmode=disable" \
./relayer-bin
```
### Orly (Badger)
```bash
cd /tmp/relay-benchmark
ORLY_PORT=7448 ORLY_DATA_DIR=/tmp/orly-benchmark ORLY_SPIDER_TYPE=none ./orly-relay
```
## Development
The benchmark suite consists of several components:
- `main.go` - Core benchmark orchestration
- `test_signer.go` - secp256k1 event signing
- `simple_event.go` - UTF-8 safe event generation
- `query_profiler.go` - Query performance analysis
- `load_simulator.go` - Load pattern generation
- `timing_instrumentation.go` - Event lifecycle tracking
- `report_generator.go` - Comparative report generation
- `relay_harness.go` - Multi-relay management
## Notes
- All benchmarks use event generation with proper secp256k1 signatures
- Events are generated with valid UTF-8 content to ensure compatibility
- Connection pooling is used for realistic concurrent load testing
- Query patterns test real-world filter combinations
