These are MIN_LATENCY, MAX_LATENCY, P50_LATENCY, P90_LATENCY, P99_LATENCY, MEAN_LATENCY and STDDEV_LATENCY. -I lvl,[,intvl] Specify the confidence level (either 95 or 99 - 99 is the default) and the width of the confidence interval as a percentage (default 10) -l testlen Specify the length of the test (default 10 seconds).

On the second node, invoke it with the IP of the first server, and the test(s) to run. The tests we are interested in are: tcp_bw and udp_bw – the rate of transfer over TCP and UDP, reported at byte-level (MB/s) and packet-level (messages/sec) Other tests are available, including UDP bandwidth and latency, SCTP bandwidth and latency, and other protocols which run on RDMA. See the TESTS section of man qperf for more details. Root Cause. qperf is a network bandwidth and latency measurement tool which works over many transports including TCP/IP, RDMA, UDP, and SCTP.
