rad_thundercat on “Long load times in the admin back-end”

WPTuner revealed that 'admin_init' is the component that's taking its sweet time: http://imgur.com/iMrF3.gif

Does that help pinpoint anything?

The site is hosted on our own boxes. I have two other wordpress sites running and have never run into this problem (although they are older versions of wordpress (2.6ish?)

I believe the only difference on this site is we put the wordpress content on one box which reads the mysql database from another box.

Although from looking at the .gif it seems that the SQL performance is fine.

Also, I'm not the IT guy here so I only have limited access to the servers (and try to understand the syntax the best I can). However, any ideas you guys have I'll be able to pass along.

Thank you!
