Things seemed kind of slow this morning so I started poking around a bit. Turns out that the server didn't like some of the new RAM that I installed yesterday and was only recognizing 256mb of it. Ugh.
I took the server down for about 10 minutes to swap out the RAM it didn't like with some other that I had around here and Voila! Now we've got 1.5gb like we're supposed to. Things should be much speedier around here now.
