Great. It's very helpful to have some comparison numbers to know what
the performance should be like. I'm going to start by getting that
server on a stable release of FreeBSD rather than a pre-release. Also a
fresh install of postfix with a default configuration just so I can make
sure nothing in my current config is messing it up. I can see what my
numbers look like then.

OK, this is smtp-source with 10 (modest) parallel sessions,
10KB (modest) messages, total 500 messages. This should typically
accept mail at 100+ messages a second finishing in under 5 seconds.
And got the following output at the end:
real 0m58.261s
user 0m0.055s
sys 0m0.126s
For what it's worth, here is one data point for Postfix 2.8-20101210
on FreeBSD 8.2-Beta1 i386 with 2 CPUs running as a VirtualBox guest,
with the smtp-source program in the VirtualBox guest. This delivers
mail to /dev/null, and ps(1) shows 10 smtpd processes. The top(1)
output spikes briefly.
/usr/bin/time ./smtp-source -t dev-n...@localhost -s 10 -l 10120 -m 500 -c

I don't have a lot of hardware lying around for bare metal testing
but I can do a temporary install on a 64-bit 2-CPU laptop computer.
