One possible caveat -- "mod_pagespeed" which is from Google dev (the start of this thread.) We tried it in a pre-production 2.4 environment, and while most of the output was well rewritten/minified/re-ordered, it put an enormous hit on server CPU cycles (on a very fast machine) -- to the point that end-user browser load times suffered. We had to drop it. (Note this was for a fairly complex perl/js site, so YMMV. Note also that Google do not *now* recommend it for 2.4, only 2.2, if I understand their notes correctly.)
- For minifying CSS/JS: look at yui compressor and google closure compiler... (Use jshint to check your js to make sure that it will merge/compress OK)
- Can use a number of build tools to do some of this auto-magically...
- Move (most) JS to the foot of the page....
Watch out with minifying HTML - there is a minor bug with most of the minifiers which which can't handle correctly ends of line after tags, and if you have gzip encoding it usually doesn't make a difference!

Hello,
I added this code on .htaccess
<IfModule mod_mime.c> AddType application/x-_javascript_ .js AddType text/css .css </IfModule> <IfModule mod_deflate.c> AddOutputFilterByType DEFLATE text/css application/x-_javascript_ text/x-component text/html text/richtext image/svg+xml text/plain text/xsd text/xsl text/xml image/x-icon application/_javascript_ <IfModule mod_setenvif.c> BrowserMatch ^Mozilla/4 gzip-only-text/html BrowserMatch ^Mozilla/4\.0[678] no-gzip BrowserMatch \bMSIE !no-gzip !gzip-only-text/html </IfModule> <IfModule mod_headers.c> Header append Vary User-Agent env=!dont-vary </IfModule> </IfModule> does not seem to make a difference!
