Solved! VMware Player is slow

This time, we will introduce solutions for when VMware Workstation 16 Player (free version) is slow.

My VMware Player was also very slow, and when I searched online I found an article that said memory-related settings could make it run faster, so I tried it, but it didn't work in my environment.

Changing the number of processor cores and launching VMware Player made no difference.

While researching and trying various things, I changed the number of processor cores in the VMware Player settings, then started it up and checked the number of CPU virtual processors in the guest OS's Task Manager, and found that although I had set it to "4," it was only recognizing "1."

If you are experiencing the same issue, try the method we will introduce here.

How to fix VMware Player slowness

Please close VMware Player.

Edit the vmx file.

The vmx file is usually located here:

C:\Users\自分のユーザー名\My Documents\Virtual Machines\仮想マシン名.vmx

or sending us a message on

C:\ユーザー\自分のユーザー名\My Documents\Virtual Machines\仮想マシン名.vmx

If the file extension is not displayed, make it visible.

How to display file extensions

If you make even the slightest mistake in editing the vmx file, it will not be able to boot, so first copy it and save it under a different name.

Open the vmx file in Notepad and look for the following:

numvcpus = "4"
cpuid.coresPerSocket = "4"
numa.autosize.vcpu.maxPerVirtualNode = "4"

Change the “4” part to the same number as the “Number of logical processors.”

If the item is not there, add it.

The number of logical processorsTask managerIn can be confirmed.

Once you have finished editing the vmx file, save it and try launching VMware Player.

Once the guest OS has started, open Task Manager and check the "Number of Virtual Processors".

If the "Number of virtual processors" has changed, the settings are complete.

If you actually open applications, files, folders, etc. in the guest OS, you will see that it is clearly faster.
