I've been considering what one should run in parallel with the speed test 
to get an impression if the speedtest impacts performance of other flows / 
realtime flows, similar to what dslreports speedtest does.

I've considered running one or several simulated voip calls (50pps) and 
record RTT, PDV, packet loss etc for this session.

It would be interesting to hear any suggestions people have for a fairly 
simple codebase that does this that can be included in these kinds of test 
clients (both server and client end, and of course one that protects 
against reflection attacks etc).

iperf3 can be used for this, but from what I can see the iperf3 server 
code isn't very friendly to multiple parallel tests or even resilient 
against hung clients that doesn't close the test nicely.

I also considered using WebRTC or VoIP libraries, does anyone know what 
RTT/PDV/packet loss data can be extracted from some common ones?
