-## 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.

-A performance benchmarking tool for Nostr relays that tests both event ingestion speed and query performance.
-
-## 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

+## 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

+```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
