New Server Box, Please Evaluate It's Performance

Those of you who've been on the server at the same time as me probably heard that MennisD and I have moved the server to a new computer. For now, it seems to be functioning pretty well, but the only way to really make sure is to stress-test it by having everyone connected and doing shit.

So, this is the thread to post about how well you think the hardware is handling running the server stuff.

Still stress testing, tell us what you think.

I'm having a heck of a time logging in today. Dunno if there's just a lot of people playing, or what.

Last night, I noticed that mine carts were REALLY freaking out with the lag. They would appear to be rapidly moving back and forth when they should have been traveling in a single direction.
Also, the hatch to my cactus trap has been mysteriously glitched for several days. I can't open it and I can't destroy it or any of the blocks immediately adjacent.
