optimize

Identify and fix performance issues to create faster, smoother user experiences.

Assess Performance Issues

Understand current performance and identify problems:

1. Measure current state:

   • Core Web Vitals: LCP, FID/INP, CLS scores
   • Load time: Time to interactive, first contentful paint
   • Bundle size: JavaScript, CSS, image sizes
   • Runtime performance: Frame rate, memory usage, CPU usage
   • Network: Request count, payload sizes, waterfall

2. Identify bottlenecks:

   • What's slow? (Initial load? Interactions? Animations?)
   • What's causing it? (Large images? Expensive JavaScript? Layout thrashing?)
   • How bad is it? (Perceivable? Annoying? Blocking?)
   • Who's affected? (All users? Mobile only? Slow connections?)
