There are massive delays and breaks in streaming video when attempting to run traffic streams concurrently. The core numbers we care about are your uplink and downlink settings. Which are?

Berlin is presently a development build. Documentation lags.=

Discussed on the list. All you have to do with Berlin is set= it up via the AQM tab.

The core numbers we care about are your uplink and downlink = settings.

Which are?

Rule of thumb is to try 85% of your rated bandwidth for thos= e and work up from there.

Enable the ADSL option.

Also on this list on berlin was discussed that perhaps htb i= s malfunctioning at very low rates.

The roadshow is on cable at 20 Mbit down 5 up. There is no m= agic solution for ever lower bandwidths than that.

I have been fiddling with much despair with a model for unde= r 4 Mbit.

Lastly efq-codel is emphatically the wrong thing in this cas= e. It is just where i stick the crazier ideas.

Please stick=A0 to fq-codel or nfq codel.
