Hmm, yea thats funky. I turn off bunk services on the xp box. I dont recall
the CPU util when immediately launching the routers, but it always seems to
peak when starting them no matter what the OS. My XP machine drops down the
CPU til to like 2-3%ish. Same as on my Ubuntu setup. Only time I have seen
it stick aroudn 30%ish (with idlepc set correctly) is when I was using USB
network cards (in windows). I have no idea why they ate up so much CPU. Some
cheap NICs I got off ebay. Switched to some PCI 4 port cards and it worked
great.
I guess Im just trying to make a point that if you have a kickass PC, your
going to be able to run any of the vendor labs no problem with XP or Linux.
