State of Performance
summary
Chrome arrives and JavaScript engines (V8, TraceMonkey, SquirrelFish) and benchmarks (Dromaeo, SunSpider) push raw browser speed, while tools like YSlow, Page Speed, Smush.it and performance linters surface front‑end fixes. Measured wins: far‑future Expires headers climb from 26% to 93%, gzip for CSS/JS goes to 100%, sprites and minification reach ~90%. Proposes public, opt‑in real‑user data, backend “lint” for MySQL/Apache, cached compiled JS/CSS, multipart downloads and prefetching; cites Shopzilla: +12% revenue, -50% ops as proof.
