2 Days ago one of the wordpress blogs I'm hosting started running very slowly, with most pages taking around 40 seconds to load. I have another wordpress blog on the same server that's an older version but loads instantly.
I've tried removing all plugins, and reinstalling wordpress and changing themes but no luck. I suicided the blog, and the still am experiencing 40 seconds load times on all pages.
I've been poking around the forum; however, I haven't seen anything there that I haven't already tried.
I installed wp-dbmanager and tried a database optimization and repair also with no luck.
The server is ubuntu linux with plenty of ram, and there is nothing interesting in the server logs.
I added the footer code to show database queries and load time. its hard to see but it's there.
The site is http://www.barber-college.org if any of you have any other suggestions it would be greatly appreciated.
