min packet ping-pong latency is the standard metric, though packets/sec
rate might be interesting as well.
# ping -q -s 1 -f hpcc001-i -c 1000000
1000000 packets transmitted, 1000000 received, 0% packet loss, time 47132ms
ipg/ewma 0.047/0.000 ms
1000000/47132 = 21.217 packets/ms
Good? Bad? Meh?
Don't use ping for HPC latency/throughput tests.
