I just set up a UT2003 server called August Knights UT2003. For those of you who play UT, please stop by the server and let me know how it performs. From what I can tell so far, it doesn't seem to stress the server much (a lot less than the crappy GlobalOps Linux server).

By the way, the Web-based administration of the UT2003 server ROCKS. I'm really impressed with how easy the server is to install and administrate (in contrast to Half-Life, which is a bit of a bear).
