High Performance Mobile
summary
Case studies show small delays change behavior — a 400 ms server delay yields measurable drops in searches and Yahoo sees 5–9% traffic loss — and fixes pay: Shopzilla speeds 7s→3s and lifts revenue 7–12%, Netflix halves outbound traffic by enabling gzip, Firefox gains 15% more downloads from a 2.2s faster page. New mobile tooling surfaces actionable specifics: blaze.io / WebPageTest captures device runs, PCAP → HAR → waterfall + PageSpeed reveals bottlenecks, and JDrop and mobile bookmarklets expose inline images (68 on iPhone) and localStorage tricks that change payloads.
