Duane, Nikos,
Thanks for your replies! To answer your questions...
A 30 minute test at 50 req/sec runs successfully.
I'm using 3 systems: one as a Polygraph client, one as a Polygraph
server,
and one as a Squid proxy.
Regards,
Bruce

I would suggest to try using different machines for the squid and the
polygraph. One machine configuration is quite painfull(having done all
these hacks you propably have seen).But make one step at a time
to find your real bottlenecks (could be the ethernet...)
average_traffic = {average_page_size *
number_of_pages_on_the_ethernet/sec}
good lack
