That's not really true -- I'm perfectly willing to spend the $100 for
a "high-end gigabit card" for every machine I have. I"m *not* willing
to spend $200-$300 or more per machine to replace motherboard and,
probably, memory and CPU as well. I don't think I'm that atypical in
that regard.
In any event, however, you're right that 32/33 machines aren't really
ideal for doing throughput tests on gig-e.
