Vmware 17 Pro very slow on Windows 11 22H2

[Ferko]

Hi,

I decided to finally upgrade to Windows 11 22H2 on my host machine. Upgrade was smooth and all seems to be running fine until I started Vmware Workstation Pro 17. All my Windows guests booted very slow and they even froze so I had to shut them down. Restart did not help and what was running smoothly before was extremely slow and unresponsive. I had to downgrade my host machine Windows back as I did not find any workaround. I found something mentioning Microsoft introduced its own Hypervisor or something but there were just some questionable workaround to uninstall/disable something.

ANyone else is experiencing the same on the latest Workstation 17 Pro and Windows 11 22H2?

Thanks.

What did you do to solve the issue?

[biowizard]

I got 17.0.1 (while I was still on Windows 10 Pro), but reverted to 16.(latest) when the Chess Titans program in my Win 7 VM crashed VMware altogether. Not my most important programme, I know, but this told me that WS 17 was not yet ready for prime time.

Then I upgraded (just over a week ago) to Windows 11 Pro. After sorting out some initial device driver issues, everything was running smoothly. Everything, that is, apart from my VMs, which not so much ran, but walked. With a limp.

Playing around with numerous settings, and scanning the web for solution, the ONE trick that DID appear to work, was disabling the Core Isolation's "Memory Integrity" setting. Switched off, and following a restart, my VMs were very much back up to speed.

The obvious question is, am I happy to leave this security feature in Windows 11 Pro disabled, just so my VMs run at full speed? Tricky one, but then again I've survived the past several years running Windows 10 (and before that, WInodws 7), without this particular protection.

I just wonder how to stop the warning exclamation mark on the task bar tray if I do decide to turn this feature off permanently ...

I have the same problem. I have Windows 11 22h2 and just upgrade to 17.0.1 to be able to install latest Win 11 Dev in a VM. Now that and my other VM Windows Server 2022 run so slow they cannot be used. Tried the power throttling fix but it did not help my system

[Cloedu72]

Are there any news, info or at least a rumor from VMWARE about this topic?
=> VMWARE at least gives us the sign that you are working on it!

Hi,
just wanted to let you know I have the same issue. Windows 11 Pro 22H2 and latest ver. of VMware Workstation 127.0.1 build-21139696

It is crazy working with this Hypervisor. Impossible to work.
Please VMware support: give us a fix, please!

Thanks

Thanks to all who are reporting these same issues.

Simply, for now, I have reverted to VMWare 16, which is not ideal, and also is a lot slower on Windows 11 than ever it was on Windows 10.

Such a shame - up until now, I have been very impressed with VMWare, both Workstation on the PC and Fusion on the Mac.

Now, for the first time, I'm beginning to consider alternative solutions.

Please, VMWare, wake up and respond to these issues!

I found the solution for my PC setup here: https://communities.vmware.com/t5/VMware-Workstation-Pro/Workstation-16pro-on-alder-lake-system/td-p...

-->

Just tell Windows to not "optimize" the application. With that setting the process will never be moved on e-cores when backgrounded.
Tested with W11 22H2

powercfg /powerthrottling disable /path "C:\Program Files (x86)\VMware\VMware Workstation\x64\vmware-vmx.exe"

powershell commands as admin:

--> sad that  this helpful solution is not comming from the VMWare support which I contacted and also payed for....

Hi,

I think, by installing VMware tools the problem was fixed for me.

Can someone else confirm this because I am not sure.

[Ferko]

Hi all,

thanks for all your proposals. I have fixed it for myself so that I have checked how many P Cores I have on my CPU and then set some lower limit on the virtual guest. With maximum number of P Cores for the guest it was unstable and slow. But with half of P Cores for virtual machine it behaves now as before.

Worked for me, Windows 11 22H2, Intel I7-12700

Here's where I go to get current builds of Windows 11.  https://uupdump.net/.  I use the Windows 11 dropdown and select 22H2 (Moment 3) which BTW is the only current distros (even moreso that what Microsoft shows on their website)  It will not throw you into the Insider as their Canary and Dev versions will (I've tested multiple vm's with each option and the Moment 3 builds are the best) I then used this build  

Windows 11 Insider Preview 10.0.22624.1610 (ni_release) amd64 within the Moment 3 on my live machine WITH Vmware 17 Pro running and 1 VM of Windows 11 Enterprise (for testing) and the overall performance of both the main machine as well as the VM's improved over 20%

This can‘t be it…

Disabling Hyper-V and everything made a small difference, but after disabling memory Integrity my vm was back at full speed…

it‘s okay when it works, but it feels wrong to disable safety features just for my workstation 17 to work.

Never would have believed it, but the power throttling change worked on my Surface 5 laptop. Thanks!

[Anderson_Sidney]

You earned your pay today!  Take the rest of the week off!  Thank you!

[DavidSvoboda007]

The first, I have switched off Hyper-V for the booting Windows 11.

But by disable Power Throttling works for me, returned speed for my VMWARE 17 Workstation Pro images. 

powercfg /powerthrottling disable /path "C:\Program Files (x86)\VMware\VMware Workstation\x64\vmware-vmx.exe"

[smileyofoz]

Yes this helped me too.  It went from being basically unusable to very zippy indeed.  Thank you!

[netravert1]

I was experiencing extremely poor performance on a brand new Microsoft Surface Pro Laptop running Windows 11. Disabling Hyper-V did not resolve my issue. Running the following command per @giopebero resolved my issues. Thank you @giopebero .

powercfg /powerthrottling disable /path "C:\Program Files (x86)\VMware\VMware Workstation\x64\vmware-vmx.exe"

I experienced the same symptoms. But disabling power throttling for VMware Workstation did not change much. However, somewhere I found the advice to update to the latest nVidia graphics driver (my machine has an RTX2050 GPU). (The source is FIX: Computer is Slow after Windows 11 22H2 Update.) In fact, this works fine, my vms now run smoothly. The driver I'm using now is NVIDIA Studio Driver – WHQL (driver version: 536.23, published 2023, June 14). Hope this helps at least those having nVidia GPU in their machine. I find this solution preferable since I don't need to change anything of the machine's security settings.

Apparently, this solved also the reported problem of downloading large files for me (Microsoft Confirms Windows 11 2022 Update Causes Performance Issues When Copying Large Files). When I setup one vm recently with MS Visual Studio (download payload of more than 7 GB) this took an eternity of more than one hour, but downloading an update today (0.5 GB), after installation of the new driver, run fast as usual - merely one minute. I suppose for quite a while I've been the only user on my VDSL2 vectoring line since my neighbours appear all to have switched to glass fibre. That is why I exclude busy connections as a cause for low download rates.

thx! that worked for me with VMWare 17 Pro an Win11 (Host and Guest)

[PeKor]

Hi, I don't know if this is helpfull but let me tell: Windows 11 Guest was painfull slow after Updating. I tried to go back with my snapshots. At least I reached the first one - a fresh installed Win11. I could do a update without problems. But: "a snapshot later" (40 Minutes later to the very first one): Win11 goes slow down again. My guess: KB5027231 from 2023-06. I could remove it on two snapshots and Win11 was ok again. Try this: Try NOT to get Win11 Update KB 5027231 (Disable Internet or use a update blocker (sordum tools) OR: Try to deinstall it. And let me know (Looking for confirmation)
