I also like the way iperf3 reports retransmits (BTW way how does it know this, I thought the kernel does the retransmits under the hood out of sight of applications). Since RRUL does not have such a nice report as iperf3 I will not be able to calculate the difference to the theoretical maximum transfer rates (also I lack insight on the ACK traffic). > I set iperf3 to run with 10 parallel streams, different MSS per test, and let > it run for 30 seconds into the rrul test. The plots are interesting, even though I have a hard time with the logarithmic scale. > So in all the tests, iperf3 session stops running half way into the rrul test.

I will have a look at the flint files, but it looks like the 1200ac does 500Mbps bidirectionally with SQM, so this looks like a decent machine for the present and (near?) future. Now I just need to wait until prices come down a tad (I hope that the 1900AC v2 release should drop the 1200ac’s process a bit). Thanks for the tests, now I know what router to try next (the edgerouterX, which I had eyed as a replacement for the shaper in the wndr3700 tops out at 130K packets per second and hence will not really work that well for a 100/40 Mbps link).
