Web Performance Kinetosis
summary
Argues that organizations misjudge user experience by testing from powerful desktops and shows concrete fixes: measure first paint, DOMInteractive, speed index with WebPageTest and Lighthouse, set performance budgets (example: BBC loses ~10% of users per extra second; DoubleClick sees 53% mobile abandonment after 3s; AliExpress cut 36% load time → orders +10%, conversion +27%). Recommends concrete optimizations (defer render‑blocking, responsive images, lazy load, caching) and demonstrates SpeedTracker — an open source GitHub Pages + Jekyll dashboard that polls WebPageTest, stores results in a repo and sends alerts.
