Monterey 12.3 on VMWare Workstation 15.5.7 on Windows 11 - EXTREMELY SLOW

[David Holland]

Hello,

 

I installed Monterey 12.3 on VMWare Workstation 15.5.7 on a Windows 11 host and it is EXTREMELY slow.

 

Not just the VM itself is slow, but it slows the host down to a crawl.  The CPU sits anywhere from between 35% to 65% with Monterey running.

 

VMWare Tools is installed in the Monterey guest OS.

 

Hyper-V is completely turned off and disabled.

 

Host computer has 64-gig ram and an i7-10750H CPU @ 2.6 ghx.

 

I have tried allocated all sorts of different memory settings and processor settings .. currently I have it set to take 16 gig ram and 6 cores on a single socket.  Changing these settings has no effect.  

 

Another interesting thing is even if I pause the Monterey virtual machine, the host OS still is at a crawl.  If I shut down the Monterey OS this allows the system to run normally.

 

VMWare runs Windows OS's like a champ.  I run everything from Windows 7 to Server 2022 on it for work and they are nice and fast.  As fast as the host.

 

I am only testing with the Monterey guest up; I don't have any other guest OS's running.

I'm trying to do the same, and Monterey is extremely low.

I have i9 12gen, 32GB of ram and I set 16GB for the VM and 6 cores.

 

Any suggestions?

VM is always slower then real machine.
