I'm running Wordpress 3.3.1 with Awake 1.3 and some popular plugins, like QTranslate, NextGen Gallery, Contact Form 7, WP SuperCache, etc.
I'm running it on a dedicated server with Plesk 9, PHP Version 5.2.4-2ubuntu5.14 / 64Bit OS with 512 MByte memory (using 71.3 MByte, 14%). Everything works fine, and pages load between 0.5-1.5s depending of the contentm, and the CPU Load of the server is between 0%-2%
I've made a copy of this installation and database for upgrade the template. I've updatde Porfolios, Widgets and others, and everything works fine, but the CPU Load increases to 99%-100%. I've create the cache folder in the theme folder, give it 777 permissions, etc and nothing change the CPU Load. I've tried to disable WP-SuperCache, and the same. And, watch this, the page load time increases up to 121.719s! When I switch to a WP Built-in theme, everyting works fine, and the CPU Load is between 0%-2% again.
Spent a lot of time on this, and don't find where the problem is. Even I've purchased Persuasion 2.0, and the problems are the same (it's the same framework).
Thanks for your help, if you need more information, please, ask me and will send it.
