Well some run dual servers, one for their site and one for their database. I don't know if this is relevant, but I created an index page for my clients, that is similar to the IIP. I used to show 47 queries when I looked at the debug statement in the footer, now it's 19 or so. My index page is based on the categories.php file with a few extras, so I had to upgrade it to be compatible with the new beta (I'm a tester) so I'm guessing a lot of things have changed to result in the big reduction in queries.
