Virtual machine runs in efficiency mode

[Marc Antheunis]

hi,

it seems that i have a win10 virtual machine that appears to run in efficiency mode according to the task manager on the win11 host.

i have another win10 vm that does not has this behavior.

but this vm that does run in efficiency mode is running so slow that even typing an email is not doable, to the point the vm even locks up...

so is there a way to disable this efficiency mode for the virtual machine (to be clear it is not the workstation process itself - which you can alter in task manager - but the actual running virtual machine)?

Tia!

Check whether this setting below is different between the two hosts. On Windows 11 host this should be checked for all VMsm unless you disabled Hyper-V. But I don't think that would make the process run in efficiency mode. Also: https://devblogs.microsoft.com/performance-diagnostics/reduce-process-interference-with-task-manager-efficiency-mode/

Don't know about no effiency modes ...

... but I just tried on a Win11 24H2 machine how different OS'ses run. There is a separate thread for that ... when it gets approved.

On a Windows 10 client, VMware installed with NO VBS Mode Host, and using standard Microsoft Windows computers (both Host and Client), Side Channel Midigations disabled ... a rather OpenGL  graphics and database intensive standalone application works just fine. VMware version is 17.5.2.
