When setting up a new dedicated server or virtual private server (VPS), the first step is to optimize the server's network, especially the speed from overseas servers to China. This can be done by running a script that updates software sources and packages, installs haveged to optimize the random number generator, and adjusts TCP parameters and enables the BBR congestion control algorithm for improved network speed.

When you get a new dedicated server or virtual server (VPS), the first thing to do is to optimize the server's network, especially the speed from overseas servers to China, which will greatly improve.

I will integrate all the things I need to do into a script, which can be executed using the following command.

wget https://gist.githubusercontent.com/taurusxin/a9fc3ad039c44ab66fca0320045719b0/raw/3906efed227ee14fc5b4ac8eb4eea8855021ef19/optimize.sh && sudo bash optimize.sh

Specifically, the following points will be addressed:

Update software sources and packages.
Install haveged to optimize the Linux random number generator, which can solve the problem of low system entropy in some cases.
Most importantly, optimize kernel network parameters, specifically adjusting some IPv4 TCP parameters, and enabling the original Linux BBR congestion control algorithm developed by Google, which can significantly improve network speed.
