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.

Welcome to Eleven Forum.

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

    fully 'Windows 11 ready' laptop. Windows 10 C: partition migrated from my old unsupported 'main machine' then upgraded to 11. A test migration ran Insider builds for 2 months. When 11 was released on 5th October it was re-imaged back to 10 and was offered the upgrade in Windows Update on 20th October. Windows Update offered the 22H2 Feature Update on 20th September 2022. It got the 23H2 Feature Update on 4th November 2023 through Windows Update.

    My SYSTEM THREE is a Dell Latitude 5410, i7-10610U, 32GB RAM, 512GB NVMe ssd, supported device running Windows 11 Pro (and all my Hyper-V VMs).

    My SYSTEM FOUR is a 2-in-1 convertible Lenovo Yoga 11e 20DA, Celeron N2930, 8GB RAM, 256GB ssd. Unsupported device: currently running Win10 Pro, plus Win11 Pro RTM and Insider Beta as native boot vhdx.

    My SYSTEM FIVE is a Dell Latitude 3190 2-in-1, Pentium Silver N5030, 4GB RAM, 512GB NVMe ssd, supported device running Windows 11 Pro, plus the Insider Beta, Dev, Canary, and Release Preview builds as a native boot .vhdx.

    unsupported machine: Legacy bios, MBR, TPM 1.2, upgraded from W10 to W11 using W10/W11 hybrid install media workaround. In-place upgrade to 22H2 using ISO and a workaround. Feature Update to 23H2 by manually installing the Enablement Package. Also running Insider Beta, Dev, and Canary builds as a native boot .vhdx.

thank you, very helpful suggestion! this is actually sufficient 99% of the time (pc start, work, shutdown, do whatever, pc start, play)

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.
