Actually several of them did mention it, but I guess you (and they)
haven't seen my talk where I show some real applications where the
rate that you can send small messages is the dominant predictor of
performance. e.g. InfiniPath is 2X lower ping-pong latency, but can
get much better than 2X the performance on real applications, if
they're streaming small messages.
