Web11 jun. 2024 · 7 The syntax is a bit different for iperf3. Example 1Mbps udp test: server side: iperf3 --server client side: iperf3 --udp --client client.ip.address --bitrate 1M What I find really interesting is the server-side doesn't start listening on the udp port until it receives the first incoming udp packet. This is weirdly unintuitive. Share Web12 feb. 2024 · When facing a client-server program, it is necessary to run two iperf3s, one on a PC as a server, and another iperf as a client to check the speed from the client to the server. To boot iperf3 in server mode: iperf3.exe -s ./iperf3 -s. To start iperf3 in client mode with certain options that we will explain later: iperf3.exe -c IP -P 50 -fg -t 5.
