qperf is giving the same strange speed:
FROM NODE1 to NODE2:
$ sudo qperf -ub 77.95.175.106 ud_lat ud_bw
ud_lat:
latency = 12.5 us
ud_bw:
send_bw = 12.5 Gb/sec
recv_bw = 12.5 Gb/sec
FROM NODE1 TO NODE2, slower and with more latency than remote host!
$ sudo qperf -ub 172.17.0.1 ud_lat ud_bw
ud_lat:
latency = 13.8 us
ud_bw:
send_bw = 11.9 Gb/sec
recv_bw = 11.9 Gb/sec
how can I check if this is due to an hardware bottleneck ? CPU and RAM are good.
