# CM Dashboard Agent Performance Benchmark

## Test Environment
- Host: srv01
- Rust: release build with optimizations
- Test date: 2025-10-16
- Collection interval: 5 seconds (realtime for all collectors)

## Benchmark Methodology
1. Set all collectors to realtime (5s interval)
2. Test each collector individually
3. Measure CPU usage with `ps aux` after 10 seconds
4. Record collection time from debug logs

## Baseline - All Collectors Enabled

### Results
- **CPU Usage**: 74.6%
- **Total Metrics**: ~80 (5 CPU + 6 Memory + 3 Disk + ~66 Systemd)
- **Collection Time**: ~1350ms (dominated by systemd collector)
