Well, not a lot.. I've got about 6 scripts running, plus a second installation for a bot that's running an additional 4 scripts. I also realized after I posted that I'd tried opening it while my anti-virus was performing a system wide scan (which really eats up the resources while it's running).

I tried it again after the scan was complete, and the delay was significantly reduced (ie: so close to immediate, that I couldn't see the difference)
