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).

Using this script you can easily test connection speed between your machine and some remote host. Example of using: $ scp-speed-test.sh user@remote_host 80000 user@remote_host is your destination host (you must have ssh-access to this host) 80000 is the approximate size of test file (in kbs), which will be received to the remote host. It is not How to use qperf to measure network bandwidth and latency Other tests are available, including UDP bandwidth and latency, SCTP bandwidth and latency, and other protocols which run on RDMA.
