Preguntas frecuentes

What is a performance budget?

Quantitative limits on metrics: e.g., LCP < 2.5s, total JS < 200KB, total CSS < 50KB, third-party requests < 10. Budgets prevent gradual performance degradation.

What's a good p95 page load time?

Under 3 seconds for most web apps. Under 1.5 seconds for e-commerce (every 100ms costs 1% in conversions). Core Web Vitals: LCP < 2.5s, FID < 100ms, CLS < 0.1.
