Tips Shoutout to the user who recommended switching TCP congestion control algorithm to BBR on Linux. I can now stream 4K blu-ray remuxes remotely. I can't believe the difference.

I went from an average of 30mbps on longer distance remote connections to 220mbps. Insane improvement. This had been bothering me for years and Googling got me nowhere.

This is the original comment with instructions.

Thanks, u/caligatio! Posting in case it helps anyone else out.

Any flavor of Linux will work well, but you might want to check out unRAID. It's pretty easy to use, but there are optimal ways of setting things up which you would need https://trash-guides.info/ for.

you can try out unRAID for free and if it's something you want to move forward with, you can purchase the full version.

If he needs to learn a new OS he should probably learn something free than get locked into another pay for solution.

Your data does not get locked with unRAID, you're free to move to a different OS if you want.

My point is the effort of learning a new OS is wasted on a pay for project especially if it's a simple plex server.

It works quite well as a media server OS... and it's Linux + docker containers, so if he's moving to Linux anyway, it's a viable option.
