HowTo - Decrease the memory usage of Spryker with Docker on WSL2

Edit on GitHub

When running Spryker with Docker on WSL2, the memory usage of VMmem can get significant, even if the memory usage of the instance is small.

This HowTo explains how you can limit the memory usage of this process.


Ensure that you are running the latest versions of:

  • Windows 10
  • Docker for Windows

Limiting the memory usage of VMmem

To limit the memory usage of VMmem:

  1. Create or update c:\users\USERNAME\.wslconfig with memory and processors parameters per your hardware and performance requirements. The following example should suit most use cases.
memory=4GB # Sets the memory limit to 4 GB.
processors=2 # Sets the number of CPU cores WSL2 is allowed to use to 2.
  1. Restart the LXSSMANAGER service:

  2. In the Start menu, enter Services and press Enter.

  3. Right-click the LXSSMANAGER service and select Restart.


Now the VMmem memory usage should not exceed the specified limit.
