Beyond Gzipping
summary
Gzipping typically shrinks HTML about 70% and speeds page loads roughly 50% over DSL and 60% over dialup in the speaker’s tests of Alexa top 10 sites loaded 100 times in IE7, yet roughly ~15% of users still receive uncompressed responses because proxies and antivirus strip Accept-Encoding. Tests show uncompressed optimization techniques yield only ~12% savings. Practical fixes: choose intermediaries that preserve compression, measure affected traffic, and consider a hidden iframe with session cookie to detect working compression.
