I think this just might be the bug (from the PHP docs):

isset() does not return TRUE for array keys that correspond to a NULL value, while array_key_exists() does.

I’ll certainly look into it once I get home.

As for your other question: it’s probably all of the plugins + the theme. K2 is query-heavy, and there are about 55 plugins currently installed – though most don’t interface with the database. NeoSmart is running WP 2.1 SVN, once it htis Beta (currently at alpha 3), the site will undergo some major mainteance and cleanup -  we just want to be sure it won’t be wasted if WP 2.1 beta breaks any of it, but I don’t think so, it’s more or less “done breaking things.”

Thanks for the suggestion, at the moment I changed the script (on our server) to not check if it’s set, haven’t had any problems since, so hopefully I can make this change to the main file as well.

Why is this site so slow? You're doing 50(!!!) queries per page! Much higher than a standard Wordpress install.   Question.

if (array_key_exists('HTTP_REQUEST_URI', $_SERVER)) {
