Interesting. I'd be interested in hearing other people's experience with this. Is this BBR stuff enabled by default on any distros?
According to multiple debian based and ubuntu based and Arch I use. No. Not default. Cubic still is.
My experience was that some days ago I was trying to make my UDP faster, but turned out found out about BBR - for TCP. Well, lucky me - currently some country away from home for family reason. Plex generally takes 40-80s to start a movie/episode for me. And measly about 10s max buffer available - and this is on a 3-5Mbps show.
After BBR (note I have to apply on Proxmox host, my container are unprivileged and can't set this themselves), I got 8-30s max to start a show/movie. And now comfortably sit between some good minutes on buffer. 15-20Mbps quality now playable.
To me personally it was black magic, and I was tossing it in just 2 days ago too
Ask more if question
If this is black magic, will I be subject to some sort of witch trial in the near future?
This is the Internet. No witch trial just witch burning.
I don't know if it is, but it is really as simple as adding to lines to a config file and restarting a service.
For example unraid (does that count as a distro?) has it enabled by default
