QoS / Traffic Shaping in Bazzite (discuss.tchncs.de)

Hey, on Windows I was a cFos Speed user for ages. cfosspeed is a 3rd party QoS software, which helped a lot for having a low latency even when bandwith is used up. I could easily play latency-sensitive games while having downloads running.

Now with Bazzite, I recognized how much good work cfos did. I had Heroic Games Launcher download a game, and play Rocket League via Steam at the same time - and ping was bad.

Is there any best practice for QoS on Bazzite? cFos basically did two things:

  • Prioritize acks over new packets
  • Prioritize packets known for gaming (e.g. due to used ports)

I do use QoS on my router, but that's not what I want: I want it explicitly on OS level. If that doesn't prioritize in the first place, it's one hop lost with bad/missing prioritization. In my example, my bad ping was actually with enabled router-prioritization. It's not enough.

Thanks for the links, I'll check them out!
