Docker Desktop kept polling VM memory usage in the background, resulting in high CPU usage · Issue #12780 · docker/for-win (original) (raw)

• I have tried with the latest version of Docker Desktop
• I have tried disabling enabled experimental features
• I have uploaded Diagnostics
• Diagnostics ID: -

Seems like Docker Desktop kept calling powershell to get the VM memory usage:

powershell "(Get-Counter -Counter \"\Hyper-V Dynamic Memory VM(DockerDesktopVM)\Average Pressure\", \"\Hyper-V Dynamic Memory VM(DockerDesktopVM)\Physical Memory\", \"\Hyper-V Hypervisor Virtual Processor(dockerdesktopvm:*)\% Guest Run Time\").CounterSamples.CookedValue"

This results in constant high CPU usage.

Information

• Windows Version: Windows 10 21H2 19044.1708
• Docker Desktop Version: 4.9.0
• WSL2 or Hyper-V backend? HyperV
• Are you running inside a virtualized Windows e.g. on a cloud server or a VM: bare metal

Output of & "C:\Program Files\Docker\Docker\resources\com.docker.diagnose.exe" check

Steps to reproduce the behavior

1. Open Docker Desktop
2. Check CPU usage
