## Performance Benchmarks

The performance test suite measures:

### Throughput
- Single insert operations
- Batch insert (1K, 10K, 50K vectors)
- Search queries per second
- Concurrent search handling

### Latency
- Average search latency
- P95 latency (95th percentile)
- Dimension impact on latency

### Scaling
- Performance across dimensions (128, 384, 768, 1536)
- Insert throughput vs. size
- Search speed vs. index size

### Memory
- Per-vector memory usage
- Total memory increase
- Memory efficiency

### Backend Comparison
- Native vs WASM performance
- Feature availability
- Optimization impact

## Next Steps

### To Run Tests

1. **Build native bindings:**
   ```bash
   cargo build --release
   cd npm/core && npm install && npm run build
   ```

2. **Build WASM module:**
   ```bash
   cargo install wasm-pack
   cd npm/wasm && npm install && npm run build:wasm
   ```

3. **Build main package:**
   ```bash
   cd npm/ruvector && npm install && npm run build
   ```

4. **Run tests:**
   ```bash
   cd npm && npm test
   ```

### For CI/CD

Add test workflow (example in `TEST_RESULTS.md`)

### For Development

- Run `npm run test:unit` frequently during development
- Run `npm run test:perf` before releases
- Check `test-results.json` for detailed metrics
