Well, if your computer grinds to a halt, you probably are. :) However,
see http://polygraph.ircache.net/cgi-bin/mail2html.cgi?fnames=20000701/816
for some suggestions on how to find performance peaks. A boiling frog
workload may be useful as well.
I assume you have patched FreeBSD according to
http://www.measurement-factory.com/docs/FreeBSD/
or, at least,

Indirectly, I guess. Your workload creates lots of network traffic
which, in turn, may cause a lot of interrupts for NIC <-> NIC driver
communication.
