Ok, Mikrotik, can we have any rough statement to this? At least if iperf was denied, or if we can expect it in v7 since its beginning or in v6 yet since 6.39.2?
To add, iperf3 should be fairly easy to add - My understanding is that it's being ported to some CPE in the states. Along the same lines, there is a binary that should be compatible for latency / Jitter called OWAMP, integration of that would be great as well assuming the clock is accurate enough to support it. I've done some work in making it work in VMs inside of other network hardware capable of running a virtualized perfSonar system in-skin. Having the binaries directly in the RouterOS would allow for a very robust meshing of tests back to a central perfSonar MU. I am in favor of having these things, it brings significant value.
Full disclosure: I work for the organization that writes iperf.
