so glad to hear the license has been fixed. carl, iperf is only used in a few of flent's tests. We trusted netperf - as did the linux kernel developers - a lot further than all the iperf variants combined - at the time we started work on flent.
I would not mind us somehow developing a drop in replacement for netperf, perhaps leveraging the irtt codebase, as I have a long standing desire to be able to reliably measure latencies and the output of TCP_INFO in "some" tool below 250us. iperf has come a long way, but getting to where I could trust the largely "academic" codebase it was would take a ton of benchmarking.
