I've been experiencing and documenting a pretty severe performance problem with SA versions 3.0.1 through 3.1x (nightly) under Solaris 8 and 9, Perl 5.8.3.
This may not be much help. I put 573 messages in a subfolder and ran the following script. I watched `prstat -n 10 2` and the typical and highest output follows. It seemed fine to me. The script, MD and everything was on a V210, which is also my courier-imap server and exports the home directories. While the script was dumping messages, courier was fine. Also clamav was running from clamav-milter and MD also runs clamav using clamd.sock. Should I disable clamav for this test?
Are you running MD with embedded perl? That may not help for your tests, but it should help in production. Have you considered using the CSW packages from www.blastwave.org? Everything that you need should be available there and I do recommend MIMEDefang instead of spamass-milter. Maybe the CSW packages are compiled differently from what you have.
Also, you did not give a summary of your hardware. My small V210 is dual CPU with 2Gb ram with RAID1 for most directories, including /export/home and using Solaris Volume Manager.

The script:
#!/bin/sh
cd /export/home/amoore/Maildir/.Mail.Hold/cur
for file in `ls`
do
cat $file |/opt/csw/lib/sendmail -f [EMAIL PROTECTED] [EMAIL PROTECTED]
done

A couple of outputs from prstat:

The MD process that seemed to do most of the work:
