iPerf (iperf) — client-server C (si) / C++ (gcc-libs) command-line utility, generator TCP and UDP traffic for testing network throughput.
Multifunction utility iPerf allows you to generate load traffic of various types to analyze network bandwidth. Supported in multithreaded mode, by running on different ports, “default” testing of a communication channel is performed from the client to the server.
iperf (iPerf2) run on two devices on the same network, the maximum bandwidth which needs to be assessed. On one device utility is run in server mode and waits for generating TCP / UDP traffic from the client to measure the maximum data transfer speed.
