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 -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
