I don't normally tweak priorities, but I don't usually have anything running when I'm
recording except Audacity, an xterm, and X.  I've found that you want to use a separate video
card rather than one that shares main memory, and you want to turn off the DRI (Direct
Rendering Interface) in the X server config file.  

Recording onto an NFS-mounted filesystem is dicey.

Perhaps you don't want to run X on the box at all.  X is network transparent so you can
display Audacity to another box on the network.  Yes this means involving another box (or a
thin client) but it _might_ give better performance.

I actually recorded about 2/3 of my CD that way -- it worked, but there was a noticable lag that made it less responsive for editing and overdubbing. My current recording box is a dual-core CPU, which gives me the best of both worlds.
