Check your php files and remember to put any templates you use in the templateused line. That might help reduce the query load a bit. Every little bit helps.

What do you mean by the templateused line?

Look at the top of any section you add a hack to. There is a line there like this:

templatesused=forumhome_forumbit_level1_nopost,

For example, the above is in index.php for the forumhome (with more template names after the first one, though).

Alright, thanks, I will look into that :)
