BBR is, in my opinion, one of the most significant improvements to networking in recent years.

I've started using it on a couple of long-range routes (e.g. Switzerland to Ireland, Frankfurt to Singapore) with Gigabit servers on the Internet, and it turns unreliable ~200 Mbit/s transfer rates into reliable > 850 Mbit/s.

And all that's needed is `sudo modprobe tcp_bbr && sysctl -w net.ipv4.tcp_congestion_control=bbr`.

Great job really!
