What is it that people so love and trust about iperf3? (this is a serious question, as I did not trust a multiplicity of iperfs methods 10 years ago, and while I know it has evolved, have not tested with it recently vs a vs flent & netperf) I was primarily looking at starlink upload speeds and delays with this docu= ment: https://docs.google.com/document/d/1puRjUVxJ6cCv-rgQ_zn-jWZU9ae0jZbFATLf4PQ= KblM/edit But I haven't refreshed it. The nice thing about testing uplink performance is you can more easily sample and control various tcp parameters like pacing_rate, etc, as well as vary the underlying qdisc. There's a flent server available at sydney.starlink.taht.net if you'd like to try it.
