Solved Win11 hypervisor cpu performance impact (~ -10%)

hi all,

I need to run docker containers on my pc (work) but also like to have maximum performance for playing games. It seems that just by having the hypervisor running (no container, no wsl) the cpu performance is about -10% (e.g. cpu-z benchmark).

reproducible by running the following commands, restart, benchmark:
* bcdedit /set hypervisorlaunchtype off -> cpu-z single core score ~920
* bcdedit /set hypervisorlaunchtype auto -> cpu-z single core score ~855

problem is, that with "bcdedit /set hypervisorlaunchtype off" docker won't start.

I thought it had something to do with virtualization based security (vbs) but using various commands to disable that (and checkinging in System Information - "Virtualization-based security": Running, Enabled but not running, ...) does not change the results (keys in HKEY_LOCAL_MACHINE/SystemCurrentControlSetControlDeviceGuard; gpedit - EnableVirtualizationBasedSecurity).
Also, changing the hypervisor scheduler type does not change anything (classic, core, root -> root was default)

It is of course not really important, probably won't notice a difference but I just don't like it (I try to optimize for peformance wherever possible).

Question: Any idea about how to not loose ~10% performance but be able to run docker containers?

I have never experienced such a loss in performance with the hypervisor enabled (at most 2-3%)

Are you comparing things on same basis i.e. running same apps in both cases. It could be Dockers Containers is causing most of the apparent loss of performance.

cpu-z is executed on the host (windows11), no containers/wsl/vms or docker software (not even the docker service) running - the only difference is windows hypervisor running or not (bcdedit /set hypervisorlaunchtype off/auto)...

Then I question cpu-z. Try running more rigorous benchmarking tools like passmark.

You can set up a boot menu to choose to start up with or without the Hypervisor. See post #2 here by Kari.

update: i had to restore a backup from 2 month back, installed all updates and I do not have this performance degredation with enabled hypervisor any longer - it seems something was wrong with my system, for whatever reason.
