It does whenever:

(a) Apache is started
(b) I am logging in to the RT UI
(c) Loading anything on the UI

then it drops down.. However, there is some considerable delay even in
loading the main page just to login.

Does my RT_SiteConfig.pm have any wild parameters that I need to work on?

Appears to happen for any page load.

As a matter of fact, I don't even have many tickets. I have been just
testing this far to see how fast the system would respond in case there were
several users.
