This is cvsup.nz.freebsd.org: [dan@cvsup:/usr/home/dan] $ sysctl vfs.vmiodirenable vfs.vmiodirenable: 1 $ uptime 1:29AM up 27 days, 14:06, 1 user, load averages: 0.00, 0.02, 0.05 As for how highly stressed this box is: $ zgrep -c "\+" cvsupd.log* cvsupd.log:5 cvsupd.log.0.gz:27 cvsupd.log.1.gz:134 cvsupd.log.2.gz:49 cvsupd.log.3.gz:22 cvsupd.log.4.gz:26 cvsupd.log.5.gz:18 cvsupd.log.6.gz:39 cvsupd.log.7.gz:24 It's a P120 with 64MB of RAM... I can't comment on the performance boost. Merely that it's been stable. -- Dan Langille pgpkey - finger dan@unixathome.org | http://unixathome.org/finger.php To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
