Also odd that TOP doesnt list how much memory is active/inactive. Aside
from that, your load is horrible, even on my dual 400 server I dont get
load that high compiling kernels, there's something really wrong, you
also have a LOT of processes running, both your sample top's have 150
processes going, do you have lots of services running on that box? On
my desktop with a few things open, web/email/icq/irc/openoffice I see
~100 procs going.
On all my machines I run 2.4.21 with the preemptive & low latency
patches, really makes the machine feel alot faster.
I've started playing with these patches too..
