 * I have WordPress running on our own server and using PHP version 5.2. Lately 
   the site has been running very slow and even slower when on the Admin pages. 
   In looking at Task Manage, PHP.exe is using all available CPU cycles. Will upgrading
   to PHP 5.3 solve this or will I screw up other items in WordPress?
 * Server is W2K Server with all service packs and security patches.
