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. >From iostat. tty cd0 fd0 sd0 sd1 cpu tin tout KB/t t/s MB/s KB/t t/s MB/s KB/t t/s MB/s KB/t t/s MB/s us ni sy in id 0 1 0.00 0 0.00 0.00 0 0.00 50.72 4 0.19 9.92 16 0.15 1 0 0 0 99 0 268 0.00 0 0.00 0.00 0 0.00 0.00 0 0.00 14.51 144 2.04 0 0 1 0 99 0 89 0.00 0 0.00 0.00 0 0.00 0.00 0 0.00 14.10 143 1.97 1 0 0 0 99 0 89 0.00 0 0.00 0.00 0 0.00 0.00 0 0.00 12.40 139 1.68 0 0 2 0 98 0 89 0.00 0 0.00 0.00 0 0.00 0.00 0 0.00 11.40 146 1.62 1 0 1 0 98 0 89 0.00 0 0.00 0.00 0 0.00 0.00 0 0.00 12.03 140 1.64 0 0 0 1 99 0 89 0.00 0 0.00 0.00 0 0.00 0.00 0 0.00 10.97 141 1.51 0 0 0 0100 The sd1 disk has 140 t/s.
