Download iperf-3.13-windows-x64.zip and save it to your computer, eg in your Downloads folder.

Right click on it, and select Extract all.

Open up the Command Prompt - Start - cmd

In the black box type: cd Downloads\iperf-3.13-windows-x64

Run an speed test by typing: iperf3.exe -c speedtest.aa.net.uk (you may need to click 'allow access' if a Windows Defender window pops up

By default, this will run a single-thread upload speedtest (sending traffic TO the speed test server).

There are variations you can do to test the speed as follows:

  • Run a single-thread Download test: iperf3.exe -R -P1 -c speedtest.aa.net.uk
  • Run a single-thread Upload test: iperf3.exe -P1 -c speedtest.aa.net.uk
  • Run a 10-thread Download test: iperf3.exe -R -P10 -c speedtest.aa.net.uk
