Btw guys, I made a small edit to the install.txt file.. so please replace the PHP code it gives you in there if you already made the change to template.php
And no do not use hellcats at the same time as it will be redundant, you only need to click "Compress Templates" after installing it, and anytime you update a template; the rest of the time your pages are already compressed.
PS. Use this in conjunction with my Other Hack that is in development for even faster pages (If you use plugins especially).
