Top 10 Lessons Learned Building PageSpeed...
summary
PageSpeed Insights and mod_pagespeed are shown working: server module auto-applies gzip, image recompression and URL signing so assets can be cached for a year yet pushed in 5–10 minutes. The Velocity schedule page renders >5s on repeat mobile view because of a 10k inline JS block and multiple round trips; critical CSS remains hard. WebPageTest plus real user monitoring experiments (30/70 split) reveal that conservative defaults still cut JPEG bytes ~76% on Chrome/Android, ~62% on iPhone, and up to 88% with no visible loss.
