That link is a fantastic read. Thanks for posting! One question I have though - why is a UDP test is better? Simply because it's inherently made up of small packets? I'd imagine the UDP iPerf test doesn't try to send large byte UDP packets, but that might be totally incorrect; I haven't used iPerf in some time.
