iperf has the notion of a “client” and “server” for testing network throughput between two systems. The following example sets a large send and receive buffer size to maximise throughput, and performs a test for 60 seconds which should be long enough to fully exercise a network.

Download this app from Microsoft Store for Windows 10 Mobile. See screenshots, read the latest customer reviews, and compare ratings for Iperf. The Iperf server communication port can be changed with the -p argument. It must be configured on the client and the server with the same value, default is TCP port 5001. The -t argument specifies the test duration time in seconds, default is 10 secs. The -i argument indicates the interval in seconds between periodic bandwidth reports. Client side: Jul 27, 2018 · To run Iperf in server mode, I will type the command “iperf3.exe -s from the Iperf directory. See image below: Running Iperf in client mode.
