I have rrul results now, both at the = same time as running iperf3. This is interesting.

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=92s 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).
