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 LibreSpeed if…
LibreSpeed suits people who want to run a speed test on their own web server or use its client options. Its stability test and optional result storage may suit users who need more than basic speed measurements.
