Performance Review
Measure and evaluate your application's performance against Google's Core Web Vitals thresholds and industry benchmarks. This review catches performance issues that are invisible during development but impact real users — bundle bloat, layout shifts, slow interactions, unoptimized images, and render-blocking resources.
When to use
Use /shiplight:performance-review when:
- Before launching or after major feature additions
- Page load feels slow but you're not sure why
- Preparing for high-traffic events
- After adding new dependencies or third-party scripts
- SEO rankings depend on performance scores
- Users report slowness or abandonment
Standards Referenced
- Google Core Web Vitals — LCP, INP, CLS (2024 thresholds)
