TLDR

Linux-NetSpeed is a deprecated shell script that enabled BBR and other network congestion-control improvements on older Linux servers, the author now recommends using built-in kernel support instead.

Things people build with this

USE CASE 1

Apply BBR congestion control to an older Linux server (kernel below 5.5) that does not have it built in

USE CASE 2

Reference the script as an example of how BBR and related kernel modules were enabled on legacy Linux systems

USE CASE 3

Understand what network acceleration options exist before deciding whether to upgrade your kernel instead

In plain English

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 The README is brief and written in Chinese, and the author notes that this script is no longer being updated.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 Because the project is no longer maintained and the primary README consists of a short deprecation notice and a download command, there is limited information about what specific options or modes the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.

Copy-paste prompts

Prompt 1
My Linux server is running kernel 4.x and I want to enable BBR, show me whether linux-netspeed is still the right tool or if I should upgrade the kernel first.
Prompt 2
Explain what BBR congestion control does in plain English and why enabling it on a Linux server can make network connections faster.
Prompt 3
I'm on Linux kernel 5.5 or newer, the linux-netspeed author says BBR is built in. Show me the commands to enable it natively without any third-party script.
