Turn on BBR congestion control algorithm for VPS with one click to speed up your VPS network

BBR is a set of TCP congestion control algorithms open sourced by Google, and has been integrated into the kernel of Linux 4.9 or above. The function of BBR is, in short, to maximize the bandwidth and speed up the VPS network. This article introduces what BBR acceleration is, how to turn on BBR on a VPS to accelerate your VPS network speed with one click, and how to check whether BBR is turned on successfully.

What is BBR acceleration

BBR is a set of TCP congestion control algorithms open sourced by Google in 2016. The purpose is to maximize the use of VPS bandwidth, increase throughput, and improve VPS network speed.

Enable BBR acceleration with one click

The following is an introduction to how to enable BBR acceleration on your VPS with one click to speed up your VPS network.

After connecting to your VPS, directly execute the following script to enable BBR acceleration with one click:

wget --no-check-certificate https://github.com/teddysun/across/raw/master/bbr.sh && chmod +x bbr.sh && ./bbr.sh

Since BBR acceleration only supports Linux kernel version 4.9 or above, the script will first upgrade the system kernel and then enable BBR. Just follow the script prompts, it's very simple and can be turned on with one click.

Check whether BBR is opened successfully

Enable BBR acceleration with one click and restart the VPS. Then connect to your VPS again and execute the following check code:

sysctl net.ipv4.tcp_available_congestion_control

If there is BBR in the returned result, it means that BBR is successfully opened, as follows (the order can be different):

net.ipv4.tcp_available_congestion_control = reno cubic bbr

BBR acceleration effect

The goal of TCP-BBR is to maximize the use of the bandwidth of bottleneck links on the network. It is produced by Google. The acceleration effect is naturally good. It has also been submitted to the Linux kernel and is very convenient to turn on. To be more specific, someone watched the video and found that the speed of a VPS with a poor original route may be increased dozens of times.
