Browsers do the unzipping in native code. You'd never notice the time it takes, even on a fairly slow machine. The packed version requires a time-consuming unpack operation in JavaScript code, whether it's zipped or not. -Mike
_____ From: Alexandre Plennevaux arf my bad, good catch karl :) , indeed i meant the packed version ! And then i guess whatever's gzipped still needs to be uncompressed by the browser which means it has a sensible influence on the performance of low specs computers , no?

Since gzip is done on the server, it can compress the full jquery, the minified, or the packed. --Karl
