-## 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. - diff --git a/cmd/benchmark/README.md b/cmd/benchmark/README.md index 8c65d65..baa639f 100644 --- a/cmd/benchmark/README.md +++ b/cmd/benchmark/README.md @@ -1,61 +1,128 @@ -# Orly Relay Benchmark Tool +# Nostr Relay Benchmark Suite -A performance benchmarking tool for Nostr relays that tests both event ingestion speed and query performance. -
