I won't get into the middle of this just yet, not having decided which dog I
should bet on yet. I've been running 2.6.21-rc6 + Con's 0.40 patch for about
24 hours, its been generally usable, but gzip still causes lots of 5 to 10+
second lags when its running. I'm coming to the conclusion that gzip simply
doesn't play well with others...

Amazing to me, the cpu its using stays generally below 80%, and often below
60%, even while the kmail composer has a full sentence in its buffer that it
still hasn't shown me when I switch to the htop screen to check, and back to
the kmail screen to see if its updated yet. The screen switch doesn't seem
to lag so I don't think renicing x would be helpfull. Those are the obvious
lags, and I'll build & reboot to the CFS patch at some point this morning
(whats left of it that is :). And report in due time of course
