:make sure you test odd packet lengths. (as in "not even")
:there are occasional bugs that turn up with that sort of thing.
Yup. Way ahead of you.
Hmm. usleep() seems to have a high granularity - only about 150 Hz.
How annoying!
I've put the linktest program up on my web site. This one adds a
'-f' option that allows you to specify to run the test as quickly
as possible with up to N packets in transit to any given host
at any given moment, default 1 (i.e. -f == -f1. Try -f2, -f3...).
