I can't speak for the iperf 3 road map.

For iperf 2.0.10 I'm actively looking to better leverage multiple cores per
threads, e.g. -P. I think a modern CPU has up to 22 real cores.

Curious to your needs.

So I think what you are really asking is whether iperf3 will support the
bidirectional tests that iperf2 supports. The answer is that no it's
not really on our roadmap at this point. It wasn't designed for this
functionality, and I think that implementing it would take probably more
effort than the principal maintainer has available. That having been
said, if someone in the community can figure out how to do either or
both of those without completely turning the iperf3 code base
inside-out, we'd be happy to discuss.

Bruce.

I haven't read the iperf 3 code much but it's primarily the multithreaded
code in iperf 2 that makes it complicated. My thoughts are to keep the
multithreading code in iperf 2 and keep iperf 3 single threaded. Then use
higher level scripts, possibly python scripts, to get the similar
functionality of of iperf 3. (Those scripts may be able to be written to
support either version as the traffic generators/sinks.)

Thanks for the feedback, Gentlemen.

I use iPerf to sequence data transmissions for a drive test tool that collects Radio Access Network (RAN) performance data on 2G/3G/4G mobility networks (LTE, HSPA, EVDO, etc.).

We’ll keep using iPerf v2 since it tests both uplink and downlink, and since the server natively allows simultaneous connections from multiple UEs (we typically test simultaneously with two UEs on different carriers).

I like the summary reports on v3 better than v2. However, they aren’t critical for this application.

I'll take a look at iperf 3 summary reports and see if better summaries can
be supported with the perf 2 -e (enhanced report) option. Can you let me
know of any specifics or any other requests that you find useful? Note: I
just happen to be now working on the sum and summary reports on 2.0.10.
