I've seen no problems at all. 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.
