# Build Options Benchmark Suite - Summary

## What We Built

A comprehensive benchmark suite (`test_github_pages_optimization.py`) that systematically tests ALL Bengal build option combinations under GitHub Pages worker constraints.

## Key Features

### 1. Comprehensive Test Matrix

- **25+ build configurations** tested
- **4 site sizes**: 50, 200, 500, 1000 pages
- **100+ total test permutations**

### 2. Resource Constraint Emulation

- **2-core CPU**: Emulated via CPU affinity (psutil)
- **7GB RAM**: Emulated via resource limits
- **Python 3.14t**: Free-threading support (no GIL)

### 3. Build Options Covered

- `--parallel` / `--no-parallel`
- `--incremental` / `--no-incremental` / auto
- `--memory-optimized`
- `--fast`
- `--profile` (writer/theme-dev/dev)
- `--quiet`
- `--strict`
- `--clean-output`

### 4. Analysis Tools

- **Results analysis script**: `analyze_github_pages_results.py`
- **Recommendations engine**: Generates actionable insights
- **Performance comparison**: Best configs per site size

## Files Created

1. **`test_github_pages_optimization.py`**: Main benchmark suite
2. **`analyze_github_pages_results.py`**: Results analysis script
3. **`GITHUB_PAGES_BENCHMARK_GUIDE.md`**: Quick reference guide
4. **`SUMMARY.md`**: This file

## Usage

```bash
# Run benchmarks
pytest benchmarks/test_github_pages_optimization.py -v --benchmark

# Save results
pytest benchmarks/test_github_pages_optimization.py --benchmark-json=results.json

# Analyze results
python benchmarks/analyze_github_pages_results.py results.json
```

## Expected Insights

1. **Optimal CI configuration**: Best flags for GitHub Actions
2. **Parallel speedup**: Expected ~1.5-2x on 2-core (Python 3.14t)
3. **Fast mode impact**: 5-15% speedup from reduced logging
4. **Memory-optimized tradeoffs**: When to use for large sites
5. **Scaling characteristics**: How each mode performs as site size increases

## Next Steps

1. **Run benchmarks** on Python 3.14t (if available)
2. **Analyze results** to find optimal configurations
3. **Update CI/CD workflows** with recommended flags
4. **Document findings** in project documentation

## Notes

- Tests will run on any Python version, but Python 3.14t is recommended for accurate GitHub Pages emulation
- CPU/memory constraints may not work perfectly on all platforms (especially macOS)
- Results will vary based on system resources and Python version
