# Benchmark Skill
This skill allows you to run performance benchmarks for the project.
## 1. Python Benchmarks
Run the Python-side benchmarks using `pytest`.
```bash
pytest -m bench -q
```
## 2. Rust Benchmarks (Standard)
Run the standard Rust core benchmarks.
```bash
cargo bench -p backtester-core
```
## 3. Rust Benchmarks (Custom Configuration)
Run Rust benchmarks with custom parameters using the helper script.
This allows you to tune the number of symbols, ticks per symbol, and batch window size.
```bash
# Run with default 'heavy' settings (8 symbols, 500k ticks)
./.agent/skills/benchmark/scripts/run_custom_bench.sh
```
You can also set environment variables manually if you prefer:
```bash
BACKTEST_BENCH_NSYMBOLS=8 \
BACKTEST_BENCH_TICKS_PER_SYMBOL=500000 \
cargo bench -p backtester-core --bench bench_core
```
## 4. Profile-Guided Optimization (PGO)
To build and benchmark with PGO (Linux/macOS).
**Note**: This process is time-consuming as it runs a full build-profile-rebuild pipeline.
```bash
make pgo
```
