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
168.100.189.20:25

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.
