Benchmark — Performance Baseline & Regression Detection

Measure performance impact of code changes and set baselines for your project.

Quick Start

Required: Bring your own benchmark tool (e.g. k6 for load testing, autocannon for API benchmarks, hyperfine for build speed).

1. Run baseline: benchmark baseline — captures current metrics
2. Make changes to your code
3. Run comparison: benchmark compare — measures impact against baseline
4. Review report: tracks deltas for Web Vitals, bundle size, build time, API latency

⚠️ Safety Warning: Load tests should not be run against production systems without explicit authorization from your team. Test against staging or local environments only.
