I have just noticed that in openSuse I have
3.5, where as on Windows I cannot find anything newer then
3.1.3, which dates from June 2016!
I still assume that
iperf is the most recommended, cross platform, tool to measure network bandwidth; especially useful for local networks, home networks, troubleshooting slow LAN.
I cannot find any other location of Windows builds other than https://iperf.fr/iperf-download.php#windows. Here, latest general version is
3.1.3. The whole project website does not seem to be updated since 2016.
Project web seems to move from https://iperf.fr/ to http://software.es.net/iperf/. Here one can find releases up to very recent
3.7; released 2016-06-21. However, when following links from there to find latest Windows binary, I ended up back at https://iperf.fr/iperf-download.php#windows.
Or what is the relation between https://iperf.fr/ and http://software.es.net/iperf/? New developing team? Fork? There is no indication of project being moved on any of the websites. Both state that: iPerf3 is principally developed by ESnet / Lawrence Berkeley National Laboratory.
