I've got a freebsd 6.2 system, dual 2Ghz 5130 cpu, 4g ram, with raid5
Adaptec 2120s, running not much more than /usr/ports/mail/imap-uw
and I'm having performance problems with only 20 IMAP users.
I'm not swapping.. cpu is mostly idle, so I figure it must be I/O
performance. Just to confirm, is that what the following show?
Thanks,
