## Frequently Asked Questions
|
|
|
|
**Q: How do I enable caching?**
|
|
A: Set `enabled: true` in `.quality/performance.json` or call `resultCache.set()` directly.
|
|
|
|
**Q: What if I have a very large project?**
|
|
A: The system scales linearly. Adjust `fileChunkSize` in config and consider database caching.
|
|
|
|
**Q: How often are caches cleaned up?**
|
|
A: Automatically on 24-hour TTL (configurable). Manual cleanup via `resultCache.cleanup()`.
|
|
|
|
**Q: Can I use this without git?**
|
|
A: Yes, it falls back to file metadata and hash comparison if git is unavailable.
|
|
|
|
**Q: How do I monitor performance?**
|
|
A: Use `performanceMonitor.getTrend()` and check the generated reports.
