How does iperf calculate bandwidth
WebBy default, the Iperf client connects to the Iperf server on the TCP port 5001 and the bandwidth displayed by Iperf is the bandwidth from the client to the server. If you want to use UDP tests, use the -u argument. The -d and -r Iperf client arguments measure the bi-directional bandwidths.
