In case you install irtt, let me know if you have any problems. It’s currently only in source form, but should be easy to install after you have Go set up. https://github.com/peteheist/irtt#installation. There are also two systemd service files in the tree in case you want to start the server at boot.

(That was also informative for me about how netperf decides when to emit a data point…)
