Would you happen to have load averages and or other system performance
measurements that we could all look at? Maybe a snapshot of "top".

I've never seen a *nix box under heavy load before and would like to
know what that looks like. I'd also like to know how much a P120 can
handle.

All the *nix boxes I've seen were running at about 1% load average or
something like 80% cpu free. My web/email server is at less then 1% load
average. It only has 3 email accounts though so not much happens on the
box.
