Make world time (-j8, src on NFS) of the SMP system STABLE kernel 27:04 Kernel with pause 26:06 I can't explain the above diference, maybe I should rerun with local src = to have a better controlled environment. On the UP machine I have a wattmeter connected an there were no change=20 in power consumption when idle. (not expected either) I'll hook up the dual to the wattmeter later today. Anything else you need to test, sorry I don't have any HTT P4 machines=20 here right now. /Martin --=20 Martin Nilsson, CTO & Founder, Mullet Scandinavia AB, Malm=F6, SWEDEN E-mail: martin@mullet.se, Phone: +46-(0)708-606170 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
