Making The Mobile Website Faster
summary
Shows concrete wins not vague tips: a 387 KB image compresses to ~170 KB saving ~56% with image tools, converting to webp often shrinks files further, and aggressive image optimization plus concatenation and minification trims payloads. Network math matters: DNS TCP and first-byte each cost ~200 ms, redirects add ~600 ms, and a 400 ms added delay cuts search activity by 0.59% in Google research while 100 ms still hurts. Practical knobs: DNS prefetch, async/defer scripts, lazy images, and installing mod page speed to automate many fixes.
