I have a OpenBSD 3.9 server with courier imapd-ssl running.
The load on the server is heavy from transactions on the
disk where I store the emails.
I'm using a Adaptec 2010S SCSI RAID card. I have tried
and tweaked the courier imap server the best I can
without any luck.

The sd1 disk has 140 t/s. CPU-load is nothing.
w:
12:35PM up 46 days, 6:15, 1 user, load averages: 7.11, 5.46, 3.09
Any ideas?
