Rui Su is a professional TCP accelerator that significantly improves bandwidth throughput and fully utilizes server bandwidth. At first, I didn't really believe it, but after posting on V2EX, many netizens responded that there is indeed a good acceleration effect for applications based on the TCP protocol. Especially many users use it to optimize ss services.

Rui Su used to be a paid software, but now it has released a free version, which can be registered and installed by any individual user. However, due to the architecture of VPS (not supporting OpenVZ) and kernel reasons, some VPS may not be able to install it. I originally tried to install it on Bandwagonhost, but failed. It turned out that Bandwagonhost is based on OpenVZ architecture. However, I successfully installed it on digitalocean, and the ss performance improved by about 10 times. It's like a black technology. Without further ado, let's start the installation.

1. Register Rui Su

First, open the Rui Su official website and register.

2. Start the installation

Here, take the Linux operating system based on KVM architecture as an example, enter the following command to download:

wget http://my.serverspeeder.com/d/ls/serverSpeederInstaller.tar.gz

Unzip it:

tar xzvf serverSpeederInstaller.tar.gz

Run the installation:

bash serverSpeederInstaller.sh

At this time, enter the ServerSpeeder installation authorization account and password according to the screen prompts, which is the email and password you registered on the Rui Su official website. It will also prompt you for some configuration options. If you are not sure, just press the Enter key all the way, so that the default configuration is used.

3. Related Commands

Restart: /serverspeeder/bin/serverSpeeder.sh restart
Shut down: /serverspeeder/bin/serverSpeeder.sh stop
Start: /serverspeeder/bin/serverSpeeder.sh start
Uninstall: ./serverSpeederInstaller.sh uninstall
Check status: service serverSpeeder status
Configuration file: /serverspeeder/etc/config

Other Notes

Xiao Z's blog has been tested with significant improvement effects. The original speed of ss was only about 50Kb/s, and after installing Rui Su, it can be stabilized at around 500Kb/s. In addition, due to my local network being too weak, the specific speed improvement situation also depends on your local network. You can install and test it specifically. PS: Rui Su has stopped registration and cannot be newly installed if you are not affected if you have already installed it.
