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 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 here right now. /Martin -- Martin Nilsson, CTO & Founder, Mullet Scandinavia AB, Malmö, 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 messagehelp
