That seems to make a big difference on some hosts. Second, try adding the flag -w2M to increase the socketīuffer sizes. Issue with the default UDP send size that was fixed inģ.1.5. Why?įirst, confirm you are using iperf 3.1.5 or higher. I’m seeing quite a bit of unexpected UDP loss.

This problem has been noted by users attempting to build iperf3 forĪndroid systems, as well as some recent versions of macOS. How can I build on a system that doesn’t support profiled executables? The last two steps are needed to produce a static executable. It appears that for FreeBSD (tested on FreeBSD 11.1-RELEASE), only

Some community-provided binaries of iperf3 for Some people are using Cygwin to run iperf3 in Windows, but not all Iperf3 is not officially supported on Windows, but iperf2 is. I’m trying to use iperf3 on Windows, but having trouble. If you want to use multiple iperf3 streams use the method described here. Recommend using iperf2 for parallel streams. Iperf3 is single threaded, and iperf2 is multi-threaded. iperf3 parallel stream performance is much less than iperf2. We recommend being familiar withīoth tools, and use whichever tool’s features best match your needs.Ī feature comparison of iperf2, iperf3, and nuttcp is available at: iperf2’sĬurrent development is focused is on using UDP for latency testing, as wellĪs of this writing (2017), both iperf2 and iperf3 are being actively iperf2.0.8, released in 2015, made iperf2 a useful tool.

Many of the feature requests for iperf3 came from the Threaded, and not worry about backwards compatibility with For this reason, it was decided to make the tool single Tool as simple as possible, so others could contribute to the codeīase. Was needed, and began development of iperf3. Iperf2’s problems, ESnet decided by 2010 that a new, simpler tool Iperf2 was orphaned in the late 2000s at version 2.0.5, despite some Iperf3 FAQ ¶ What is the history of iperf3, and what is the difference between iperf2 and iperf3?
