I've been having issues with the response time of my blog (www.whereamifrom.net), including the admin module. Here's what I've tried:
Checked with my ISP for server/db performance issues (they say everything is fine)
Tested response time with other php scripts (all fine)
Disabled all widgets
Reverted back to classic theme
Wp-cache helps with the blog after you view each page once, but the admin module is very slow. Any ideas?
