Consider tweaking more options

[ndfred]

A good iPerf testing article that goes into the different advanced options. Window size and UDP might be interesting to surface in the UI.

Jitter recommendations:

Ideally, jitter should be below 30ms. Packet loss should be no more than 1%, and network latency shouldn’t exceed 150 ms one-way (300 ms return).

Test run with 20 Mbits/s (but unidirectional and single stream) to match a FaceTime connection:
