Introduction<\/h2>\n

Sometimes, you may want to limit the CPU usage of a specific process on your to prevent resource hogging or maintain server performance. CPULimit is a tool that allows you to limit the CPU usage of processes. This guide will show you how to use CPULimit on Windows VPSto restrict CPU usage effectively.<\/p>\n<\/section>\n

\n

Step 1: Install CPULimit on Windows<\/h2>\n

CPULimit is a Linux utility, and it is not natively available on Windows. However, you can use Windows VPSSubsystem for Linux (WSL) to run CPULimit on your .<\/p>\n

Follow these steps to install WSL and CPULimit:<\/p>\n

    \n
      \n
    1. Open PowerShell as Administrator and run the following command to install WSL:<\/li>\n<\/ol>\n<\/ol>\n
      wsl --install<\/code><\/pre>\n
        \n
          \n
        1. Restart your system when prompted to complete the WSL installation.<\/li>\n
        2. Next, install a Linux distribution like Ubuntu from the Microsoft Store.<\/li>\n
        3. After installation, open the Linux terminal and set up your user account.<\/li>\n
        4. Now, update your package list by running:<\/li>\n<\/ol>\n<\/ol>\n
          sudo apt update<\/code><\/pre>\n<\/section>\n
          \n
          Step 2: Install CPULimit on Ubuntu via WSL<\/h2>\n
          Now that you have WSL and Ubuntu installed, you can install CPULimit:<\/p>\n
            \n
              \n
            1. In the Linux terminal, run the following command to install CPULimit:<\/li>\n<\/ol>\n<\/ol>\n
              sudo apt install cpulimit<\/code><\/pre>\n
                \n
                  \n
                1. Confirm the installation by typing ‘Y’ when prompted.<\/li>\n
                2. After installation, you can verify the CPULimit version by running:<\/li>\n<\/ol>\n<\/ol>\n
                  cpulimit --version<\/code><\/pre>\n<\/section>\n
                  \n
                  Step 3: Limit CPU Usage with CPULimit<\/h2>\n
                  Now that CPULimit is installed, you can start limiting the CPU usage of any process. Here’s how to do it:<\/p>\n
                    \n
                      \n
                    1. Identify the process ID (PID) of the program you want to limit. You can do this by running:<\/li>\n<\/ol>\n<\/ol>\n
                      ps aux<\/code><\/pre>\n
                        \n
                          \n
                        1. Find the PID of the process you want to limit.<\/li>\n
                        2. Use the CPULimit command to restrict CPU usage. For example, to limit a process with PID 1234 to 50% CPU usage, run:<\/li>\n<\/ol>\n<\/ol>\n
                          sudo cpulimit --pid 1234 --limit 50<\/code><\/pre>\n
                            \n
                          1. This command will limit the process to 50% CPU usage. You can replace ‘1234’ with the PID of the process you wish to limit and adjust the percentage as needed.<\/li>\n<\/ol>\n<\/section>\n
                            \n
                            Step 4: Run CPULimit in the Background<\/h2>\n
                            If you want CPULimit to run in the background and keep the process limited even after you close the terminal, you can use the following command:<\/p>\n
                            sudo cpulimit --pid 1234 --limit 50 --background<\/code><\/pre>\n
                            This will limit the process in the background without requiring the terminal to remain open.<\/p>\n<\/section>\n
                            \n
                            Step 5: Limit CPU Usage for New Processes<\/h2>\n
                            If you want to limit CPU usage for a process before it starts, use the following command:<\/p>\n
                            sudo cpulimit --exe \/path\/to\/executable --limit 50<\/code><\/pre>\n
                            Replace \/path\/to\/executable<\/code> with the actual path of the program you want to run and limit the CPU usage to 50%.<\/p>\n<\/section>\n
