On +3: I was able to get rrul to sort of fail on the ath10k also in the same way. no kernel messages, but it had trouble establishing the control channel after rrul ran, on rrul_be. it could be osx going to hell, I can only get it to happen after pounding it flat with a dozen other tests first. If I just run it after a period of idle, can't get it to fail. The ath9k test on the same hardware I just did of your +3 completed all tests (except for rrul, same as above) and throughput was a bit better than the last series I'd done (I switched channels to one less busy at this hour of the day). No kernel messages. There is an interesting pattern emerging relative to the number of flows (see attached), that I guess I'll have to go check against linux<->linux's tcp... I've always kind of wondered about block acks vs del tcp acks.... we're not out of cpu at this lower rate, so it shouldn't be fq_codel's cpu usage at fault... The quantum is writable? Cake works, too. While I won't certify this new hardware as ready for wide testing by others, yet, it really does look quite good for the basic stuff we care about. I will fire up a long series of 300 tests on this, move back to the archer, and see if I can sort through the x86 patchset... and get in a swim. Happy. thx. a nice labor day....
