Maybe some wise soul out there will recommend another benchmark,
but I've seen "ttcp" mentioned enough it seems acceptable I think.

Anyway, I don't know how to achieve what Matt just mentioned, but
if you can do so by specifying a larger buffer at the application
level, then maybe it would be interesting to see what happens over
a longer period and with different data sizes,

	e.g. -l 32768 and/or -n 4096 or -n 8192 etc.
