But only measurements can tell. So on Hnymans community openwrt build a few fortunate ones on = excellent lines seem to get decent results even at 110-120 Mbps = combined: https://forum.openwrt.org/viewtopic.php?pid=3D250989#p250989 and: https://forum.openwrt.org/viewtopic.php?pid=3D251013#p251013 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 busts 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 can 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 opportunity, no?) My own = internet link is way to slow to test this...
