[SOLVED] Why is my new atahualpa site going so sloooooow?

I have several sites running atahualpa that are running fine.

The particular site in question runs fine when I switch it to another theme.

I've tried shutting off all plugins, and there is a cloud caching service running on it.

It's been running slow as long as I can remember so I can't pin-point anything specific.

I have several custom page templates, very few plugins, less photos than I've seen on much faster sites.

Any ideas? http://www.millenniumrun.com thanks,
