Google BBR uninstall tutorial sharing, with other acceleration methods and one-click installation method

Google BBR is a commonly used TCP acceleration solution. Based on BBR acceleration development, there are BBR Plus, Magic BBR, etc. Other TCP acceleration strategies include Ruisu, etc. When installing these acceleration methods, we need to first Uninstall BBR. Below I will share with you a BBR uninstall tutorial and a four-in-one VPS acceleration tutorial.

1. BBR uninstallation steps

The VPS acceleration strategies shared in many tutorials are BBR, so the first TCP acceleration solution that many people come into contact with is also BBR. If they later find that BBR acceleration is not suitable for them, they may want to turn off BBR. Here are the steps to turn off BBR. / Uninstall BBR.

1. Delete BBR acceleration code

Edit the sysctl.conf file:

vi /etc/sysctl.conf

Comment or delete the code related to BBR acceleration:

# net.core.default_qdisc = fq # net.ipv4.tcp_congestion_control = bbr

Execute the following command to save the modification of uninstalling BBR acceleration:

sysctl -p

Finally restart the VPS (reboot).

2. Check whether BBR is successfully closed

We can use the following command to check whether BBR is successfully closed:

sysctl net.ipv4.tcp_available_congestion_control

If there is no bbr in the returned result, it means that BBR is closed successfully:

net.ipv4.tcp_available_congestion_control = reno cubic

2. Other VPS acceleration strategies

Previously, this site also shared with you a four-in-one script. In addition to BBR acceleration, there are also BBR Plus, BBR magic modification, sharp speed, etc. You can refer to "BBR original/magic modification/Plus + sharp speed four-in-one" A script".

Of course, in fact, the most important factor affecting VPS speed is the influence of VPS lines. For example, American VPS recommends choosing CN2 GIA VPS: "The Best CN2 GIA VPS Recommendation and CN2 GIA Merchant Compilation in 2020", if you have enough budget , you can also choose a datacenter that is physically close to you, such as Hong Kong VPS: "Recommendation of the best Hong Kong VPS in 2020 and compilation of Hong Kong datacenters and merchants".
