In home streaming is basically a high bandwidth low latency way of streaming a game so you can play it on another machine. I'm not sure if this is the best list to talk about this on, but since it involves wifi, fq-codel, and cake, this seems like the best place maybe, I did start by talking about this on the forums, but I think I've basically reached the end of what documented configuration can do on the current LEDE, and perhaps what can be done currently period. That said maybe I can offer up this use case and help things improve in the future.

I've actually managed to get game streaming mostly smooth, but there's still an occasional stutter (latency increase from ~5ms to around 100ms, then it goes away again) that I haven't figured out. happy to provide more information if it'll help this use case. note, the additional options mentioned in the forum on src/desthost seem to actually make things worse.
