This is in X with kde loaded, gkrellm running (reported ~280 procs at height of make), xmms running. Only one skip in play back, and the mouse jumped a bit sometimes. :)
Now, it's off to build a kernel w/o the stats, to see it that changes anything....and it does. The sound didn't skip this time, and the proc load "only" got upto ~200.
This is a AMD Athlon 800 w/512 Meg ram, ext3 root, reiserfs /usr on sw raid0 over two sw raid1s.
