Pick iPerf2 if…
It suits people who need to measure TCP or UDP network behavior across supported platforms, including self-hosted setups. The socket-level measurement limit and lack of interoperability with iPerf3 matter when choosing it.
Pick M-Lab NDT if…
NDT suits people who want to measure connection speed, and researchers, operators, regulators, or public-interest groups examining Internet performance. Its public results also make the connecting IP address visible indefinitely.
