I tried it out on my UP machine - BTW on line 312 there's a missing ``);'' - and the results were, not to pull any blows, catastrophic. Running X I started a ``make buildworld'' in an aterm and immediately observerd: o the cursor lagged way behind mouse movements o switching desktops allowed me to observe in detail how various applications repaint themselves - it was that slow o mozilla was totally unusable With the current scheduler interactive applications are still quite snappy. I never observe any of the above mentioned problems with it. I know this is a WIP, but I thought I'd report my observations. This on an XP 1800+ with 768MB of memory and (fairly) fast SCSI disks. -------- Gary Jennejohn / garyj@jennejohn.org gj@freebsd.org gj@denx.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
