Limiting WSL 2 RAM And CPU - gecko-8/devwiki GitHub Wiki

Up

1. At the root of your C: drive (or whatever drive Windows boots from) add a .wslconfig file.
2. Edit the file to contain the following (setting whatever RAM and CPU limits you want):

   [wsl2]
   memory=4GB # Limits VM memory in WSL 2 to 4 GB
   processors=2 # Makes the WSL 2 VM use two virtual processors
   

3. Restart WSL from an admin PowerShell with the command:

   Restart-Service LxssManager
   

   NOTE: If running Docker, you will likely get an error asking to restart Docker.
