I recently found this on Reddit while looking into why jellyfin is effected so much by latency. I found that this worked and thought I would share it because it is generally applicable, takes five minutes to setup, and helps a lot with bandwidth on higher latency connections. I admit I am not sure of the technical stuff behind this, so if anyone would like to chime in that would be much appreciated.
Cool writeup. I remember implementing BBR many years ago when I was trying to bypass the Great Firewall for an extended stay. Helped deal greatly with the huge congestion on Chinanet backbone at the time, but it's less of an issue these days now that foreigners can use CN2.
