 * Hi guys,
 * I can not publish any new pages to my site simply because every time I open /
   wp-admin/page.php and try to do this the CPU is ready to explode! Normally when
   the CPU usage is nearly 100% the site is down. The sevrer is a dedicated one 
   2GB RAM.
    I’ve got wp-super cache and some other tweaks installed, but nothing
   helps. The site has appr 5000 posts/pages and everyone of them with at least 
   4 custom fields – I’m wandering if this is the problem!
 * Any advice would be much appreciated.

 * I’ve solved it, but if someone else is experiencing the same: It’s the permalink
   structure: /%category%/%postname%/

   Changing the permalink to /%monthnum%/%year%/%category%/%postname%/ solved the
   problem 🙂
