iperf3: A TCP, UDP, and SCTP network bandwidth measurement tool Summary iperf is a tool for active measurements of the maximum achievable bandwidth on IP networks. It supports tuning of various parameters related to timing, protocols, and buffers. For each test it reports the measured throughput / bitrate, loss, and other parameters.

• Windows: iperf3 binaries for Windows (built with Cygwin) can be found in a variety of locations, including https://files.budman.pw/ (discussion thread).

For ten seconds report Mbit/sec

Iperf is a widely used tool for network performance measurement and tuning. It is significant as a cross-platform tool that can produce standardized performance measurements for any network. Iperf has client and server functionality, and can create data streams to measure the throughput between the two ends in one or both directions. Typical Iperf output contains a time-stamped report of the amount of data transferred and the throughput measured.

Free and openly available, Iperf is a command line tool useful for measuring network performance. In my last post, I introduced some basic command line instructions to run Iperf between two endpoints and showed how the tool can be used to generate and measure both TCP and UDP performance. This time, I’ll discuss Iperf’s graphical cousin: Jperf.
