What is linux-netspeed?

Linux-NetSpeed is a shell script collection aimed at speeding up network connections on Linux servers. It bundles several network acceleration methods that are commonly applied to Linux systems, particularly BBR and related congestion control algorithms. BBR is a technique built into the Linux kernel that improves how a server manages outgoing data, which can result in faster and more stable connections. The README is brief and written in Chinese, and the author notes that this script is no longer being updated. They recommend that users running Linux kernel version 5.5 or newer rely on the built-in BBR support that ships with those kernels instead of using this script, since the newer kernels handle it natively. For those who still want to use this tool, the setup involves downloading a single shell script called tcp.sh and running it with a couple of commands in the terminal. Because the project is no longer maintained and the primary README consists of a short deprecation notice and a download command, there is limited information about what specific options or modes the script provides beyond the general network speed improvement goal.
