Hacking Web Performance
summary
Median First Contentful Paint ~2.4s and median Time To Interactive ~8.9s, with some landings near 22s, so expect concrete, measurable wins not vague tips. Covers using 14.6 kilobytes as a TCP slow‑start budget, enabling HSTS to avoid redirects, Brotli and newer image compressors, bundling + preload + importance, lazy loading and preload for responsive images, service worker patterns like stale‑while‑revalidate, Client‑Hints and reactive server decisions, and practical rollouts for HTTP/3 (QUIC) and Chrome Lite Pages with numbers and implementation notes.
