Learn how to measure TCP/UDP, throughput, loss and delay with iPerf, an open source network testing tool.

Scott Reeves demonstrates the use of iperf, which provides basic information on throughput, packet loss, and jitter to help you troubleshoot UDP and TCP issues.

For example, as the above screenshot shows, the default TCP buffer length (which I used) is 8 Kbytes. Not explicitly revealed in the Iperf GUI is the additional fact that when not otherwise specified, ...

Scott Reeves shares the wireshark filters that helps you isolate TCP and UDP traffic.

Sure enough, with the default iPerf 1.7.0 settings we saw severe asymmetry in the links in dual-send mode -- 92Mb/s going out, but only ~30Mb/s coming back.
