Sound stutters and mouse slows way down

I am using a Gigabyte server/workstation board for my desktop.  It is 
a dual socket A board.  I have 2x 2400MP athlons in it along with 768 
megs of RAM.  My load averages tend to be around  1.00 -> 3.00 with 
CPU utilization 30-40% idle.

My problem is that cvs, bzip2/bunzip2, and tar bring my system to it's 
knees.  Sound stutters badly even though I have set XMMS to use 5 
megs of buffering.  The mouse slows way down and gets jerky as well.  

I am running 5.3-RELEASE-p6.

Here's a dmesg:
