When we use foreign servers or VPS, we often encounter problems such as slow download speeds, and we can solve this shortcoming through special software. Of course, the solution is only temporary. If you want to completely solve the problem of slow downloads and uploads, you still have to spend more money to upgrade your bandwidth! Today I will bring you a tutorial on compiling, updating and installing the latest kernel of BBR2-Kernel. Perfectly speed up your server and VPS.

Notes before installation:

• Before replacing the kernel, please ensure that the VPS has the VNC function. If it cannot be started, please go to the VNC page to manually switch the kernel startup
• This article does not guarantee whether the kernel will run 100% perfectly
• If you encounter the problem of kernel startup failure, please VNC to enter the server to manually select the kernel and delete the default kernel that reports the error
