If your host drive is a hard drive (not SSD), let the machine fully start (may take 10 minutes) and re-evaluate.

If the performance remains slow, defragment the machine using VMware Defrag (machine disk properties.

Now move the machine to a USB hard drive. Make sure you do this correctly.

Now defrag the main drive. When done, move the machine back to the host and test.

How much memory does the host have ?

What CPU is in the host ?

What disk system is in use by the host and VM ?

What is the VM ?

Have you configured the VMware Workstation preferences to Reserve ALL Memory for VMs ?

VMware Tools are for features and should not slow down a machine if not installed. That is my experience with VMware over many years.

VMware Tools is a suite of utilities that enhances the performance of the virtual machine's guest operating system and improves management of the virtual machine. Installing VMware Tools in the guest operating system is vital.

@Shaun Vermaak How does it do this ?

Please clarify this statement, with reference to VMware Workstation?

Overview of VMware Tools

VMware Tools is a suite of utilities that enhances the performance of the virtual machines guest operating system and improves management of the virtual machine. Without VMware Tools installed in your guest operating system, guest performance lacks important functionality. Installing VMware Tools eliminates or improves these issues:

Low video resolution
Inadequate color depth
Incorrect display of network speed
Restricted movement of the mouse
Inability to copy and paste and drag-and-drop files
Missing sound
Provides the ability to take quiesced snapshots of the guest OS
Synchronizes the time in the guest operating system with the time on the host

Okay, so the host has 24GB of memory.

and what setup does the VM contain ? e.g. VM specifications, in terms of memory and CPUs ?

and all VMs are slow ?

what if only a single VM is in use ?

and any reason you are using VMware Workstation, a type 2 hypervisor, an application on Windows 10, rather than Client Hyper-V, a type 1 hypervisor, which will give far better performance.

Same if only single VM is in use

I was not aware of Client Hyper-V at the time of purchase.

It's been in Microsoft Windows since Windows 8.x Pro.

Not need for any additional hypervisor, or installed application, especially a type 2 hypervisor.

Okay, so if you have a Core i7, with 24GB RAM, and SSDs, and a single VM is SLOW.

Have you reserved RAM in Workstation ? for running these VMs.

I have no issues with a 2GB VM, on a Core i7 laptop, running Windows 8.1 Pro,

Disk I/O is usually the bottleneck, not CPU or Memory, unless you've over done it, what type of slowness are you encountering ?

and what I mean by that is you've really overcommited vCPUs and Memory in the VM.

You've not got BIOS set to Battery Mode, or Low Performance, Energy Savings.

Power off and restart the host computer.

Power on the host computer, start VMware Workstation, and try a single VM.

Did not help.

I noticed that ruing vmware spikes up the I/O extremely high (over 120 ms) as soon I turn it off is drops to 0 (I only measured the drive the VM or saved on)
