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 believe it will result in like 10% additional overhead, which may be bad on metered connections, but I am not aware of any situation that results in decreased performance. I don’t really know much about this so if anyone would like to correct me, please do.
