I am interested in feedback on the testing output. My goal is to add a

So that is showing up to 10s of *seconds* of latency, right? (I'm not
sure I'm reading the units right).
Yes, 10 seconds of latency. My traffic generator is using pfifo-fast,
RENO, and default socket sizes, so it can be at least part of the problem.
That's so much latency that you may as well be down.
Please look at the make-wifi-fast mailing list and the tests that are being
done there. they show latency spikes as well as throughput, and show how it is
very
possible to get low latency without affecting throughput (in some cases,
throughput actually increases)
I did some tcp/udp mix, tcp only, udp only download tests, with fq_codel and
fifo-fast on the traffic
generator. AP was un-changed, seems LEDE uses fq_codel by default. Generator
is using 4.4.8+ kernel, and it looks
like fq_codel works nicely!

We'll run some tests on some of our higher-performing APs and see if fq_codel
works well there
too when we get a chance....
Thanks,
Ben
