docker hogs Windows resources under WSL2

[psychemedia]

Via a student:

• Running Docker under WSL may cause your hold computer to slow down [contributed]: a fix described in How to Stop WSL2 from Hogging All Your Ram With Docker suggests:

1. creating a .wslconfig file in c:\users\*your your profile name* containing the lines:

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

2. from Powershell with admin rights, restart WSL2 by typing: Restart-Service LxssManager

You should be okay setting memory=4GB although you may find things, particularly in the second half of the course, run more smoothly by setting memory=4GB
