- **Storage**: 100MB for installation, 500MB for cache/logs
- **Network**: Broadband internet connection recommended
- **CPU**: Modern multi-core processor recommended

### Performance Metrics
- **Startup Time**: < 5 seconds
- **Analysis Time**: 10-30 seconds per cycle
- **Memory Usage**: 50-100MB typical
- **Network Usage**: 1-5MB per analysis cycle

### Optimization Tips
- Use appropriate alert cooldown periods
- Enable caching for frequent API calls
- Adjust logging levels for performance
