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

Assess Performance Issues

Understand current performance and identify problems:

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
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?)
