how to limit CPU for vmmem process

In windows 10 machine I have installed Rancher Desktop which requires WSL2.

Whenever I started the Rancher Desktop, the vmmem process started high CPU utilization and going till 100%. I am seeing article to limit the memory using wslconfig file (c:\Users\damie\.wslconfig), but only the memory.

Is there way to limit CPU as well?

[wsl2]
memory=4GB

Thanks.

Solution

  • You can use "processors" which can be used to set how many cores the WSL2 has available. For example:

    [wsl2] 
memory=16000MB    #Limits VM memory in WSL 2 to 900MB 
processors=8    #Makes the WSL 2 VM use eight virtual processors

    Here's the documentation from Microsoft.
