Already working with wordpress and I can testify that this plugin is awesome, since I've been using it, my wordpress is way faster than vbulletin. It combines javascripts & css. My request is to make this awesome resource available to vbulletin 3/4 users.
This should be a good start for coders.

PHP Speedy is a script that you can install on your web server to
automatically speed up the download time of your web pages. Here?s an example, from a test page:
Before PHP Speedy - 14 requests that took 4.44 seconds
After PHP Speedy - 4 requests that took 1.1 seconds

PHP Speedy automatically joined together all the appropriate files and compressed them, greatly reducing the load time of the page. Let?s see what Yahoo?s Y-Slow makes of this:
Before PHP Speedy - Grade F (44)
After PHP Speedy - Grade A (96)
