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.

I skimmed through it and have no idea what BBR stands for.

It's an algorithm for determining how fast to upload packets. This article just talks about how to enable it.

Here's the Wikipedia section about it: https://en.wikipedia.org/wiki/TCP_congestion_control#TCP_BBR

The gist is that instead of only throttling upload rate based on packet loss, BBR constantly measures roundtrip delay (ping) to determine how much bandwidth is available.

Thank you! I hate unexplained acronyms

It is explained in the article though...

Ahh yes, the first time it is defined is in the conclusion after being used 25 times previously in the article.
