Website performance from user perspective
summary
Shows a concrete 360° test strategy that replaces synthetic-only stats with real browser measurements and client-side timings, and demonstrates the surprising gaps between tool outputs — 68 ms vs ~300 ms processing and cases where rendering takes 7+ seconds despite fast downloads. Uses specific tools and APIs: YSlow, PageSpeed Insights, WebPageTest, JavaScript Resource and Performance APIs plus guidance on when to use load generators, what metrics to collect, and how to report real user experience.
