I run a site with around 12 WordPress installs and have been having major issues lately with my dedicated server crashing because of a abnormally high load of PHP/MySQL queries. My web host is convinced that WordPress or something in one of my themes is the cause for this issue, but I am running WP Super Cache for every install which is another part of the puzzle. If my host admins are correct, and WordPress is the cause what should I be looking for? Any suggestions at this point would be greatly appreciated. Basically my sys-admins are stating that every user visiting my site is spawning about 200+ PHP/MySQL queries.
