Docker Desktop kept polling VM memory usage in the background, resulting in high CPU usage #12780
Description
- 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
- Open Docker Desktop
- Check CPU usage
