multiple CPUs and vmstat
I'm running 7.0 on i386. I'd like to see multiple cpu stats in vmstat. vmstat procs memory page disk faults cpu r b w avmfre flt re pi pofr sr ad0 in sy cs us sy id 0 0 0 398000 77144 7298 1 1 0 5686 12 0 117 18938 1758 32 11 58 The formatting got whacked, sorry. I looked at several man pages and couldn't find any other stat program that showed multiple processors. I have a system monitor running under SuperKaramba, but on a Hyperthreaded system, it shows both processors with identical CPU percentages. I had sent a bug report to KDE, but the guy that picked it up couldn't understand my point. Which is, since a hyperthreaded CPU is actually two pipelines sharing a common execution unit, the "best" it could be doing is complementary precents, i.e., if one CPU is 60% utilized, then the other CPU couldn't be any better than 40 % utilized. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

CPU idle time doesn't measure how well your system is performing, it only tells you when it's reaching capacity in its current configuration. You need to compare how much work it can do with/without HTT (e.g. how many messages can it process/hour, if you have a more or less constant input?) Kris pgprBFcrS2nn4.pgp Description: PGP signature
