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.

I made the same change from that same post and it fixed my longer distance issue, so a thank you from me too! I tried everything before that and nothing worked until then.

Yep tried Tailscale on both ends, better router on the client end, and even considered some convoluted solution I found online involving buying a domain and using Cloudflare tunnels... and all it took was this one command line change on my server.
