Sorry there are two conversational threads here on hynyman s= thread they are benchmarking vs an anctiontec.

Also it does seem like fiddling with the burst parameter to = htb seems warrented.

It looks to me as if the actiontec has pretty good qos all b= y itself.

=C2=A0 =C2=A0 =C2=A0 =C2=A0 So on Hnymans community openwrt build a few for= tunate ones on excellent lines seem to get decent results even at 110-120 M= bps combined:
https://forum.openwrt.org/viewtopic.php?pid=3D250989#p25098= 9
and:
https://forum.openwrt.org/viewtopic.php?pid=3D251013#p25101= 3
I have no idea why and both lines were reasonably well-behaved even without= any AQM/QOS...

Also I wonder whether when we increase the quantum for higher rates to give= HTB some breathing room, whether we also should increase burst and cburst?= My hunch is that quantum affects the switching between the leaves, while b= usts and cburst should allow to dump more data to lower layers inside each = leaf qdisc. And since we are running behind, maybe taking a bigger shovel c= an help some. (I assume this needs to be titrated not to kill latency under= load, but if we can only effective have HTB execute x times per second we = can easily afford to dump line-rate/maxHTB_iteratin_rate bytes per opportun= ity, no?) My own internet link is way to slow to test this...

Best Regards
