performance-testing

Performance testing baselines measure real-world frontend and backend metrics like p50, p95, and p99 percentiles. This provides baseline protocols and budgeting rules to compare against before changing code, preventing regressions.

Core Web Vitals budgets enforce targets for LCP, FID/INP, CLS, and TTFB within CI/CD pipelines. This provides example configurations using k6, Artillery, and Lighthouse workflows to trigger automated regression checks and alerts for budget overruns.

Identifying performance bottlenecks requires measuring real-world metrics across frontend and backend endpoints. This applies testing end-to-end, establishing baselines and budgeting rules to pinpoint where API or web application latency originates.

Validating a new feature rollout requires comparing current performance against an established baseline. This applies baseline protocols to measure frontend and backend endpoints, triggering alerts if Core Web Vitals or API budgets are exceeded.

Performance testing supports integration with k6, Artillery, and Lighthouse workflows. No specific dependencies are required to start; it provides baseline protocols, budgeting rules, and example configurations to implement automated regression checks.

Measuring p50, p95, and p99 percentiles establishes a performance baseline to validate API and web application behavior. This prevents regressions and budget overruns by ensuring you measure and plan optimizations before changing code.
