I have been chatting w= ith a startup in the Multi-User Dwelling networking operations space, and t= hey seem to really be attracted to Ubiquiti Unifi systems. I can't blame th= em for wanting a comprehensive and evolving system.

But on the questions related to buffe= rbloat and making wifi both low latency and fast, I really don't know much = about these products. (I have a Unifi 10 Gb/sec switch as my home/lab fiber= backbone, but that's not really relevant to answering this question).

So, since you, Da= ve, and others have been talking about real-world fq_codel etc. and faster = wifi scheduling, does anyone know what the status at Ubiquiti is?

I know some here run Op= enWRT/LEDE on Unifi APs, but that's not my question, really.

Any knowledge out there?

(I'd like to reco= mmend that they run some actual load tests - flent RRUL, etc. - but I think= they might need some help).

Personally I have n= o stake whatever in their use, but I'd love to get someone to start solving= the bloat and queueing/scheduling problems.
