How much is the difference in Windows OS performance between a physical machine and a virtual machine (VMware ESXi)?

Question

Windows

Good afternoon. The question is to those who have encountered, have experience, checked.

If you work with a Windows machine via RDP, will there be a noticeable difference in performance if you use virtualization?

That is, for example, if you take a physical machine, for example, with an i3-6100, 8GB DDR3l and an SSD drive, and make a virtual machine of the same characteristics on ESXi (say, on the same hardware), despite the fact that apart from this virtual machine, no other virtual machines will not be used / take away resources. Will the system run slower on a virtual machine compared to a physical one, when working through a thin client via RDP?

Thanks in advance for your replies.

Answer 1

There will be a difference.
Tangible or not - depends on your tasks.
IMHO, not a significant difference.
Just try.

Answer 2

in the version you proposed, the difference will be so insignificant that you won’t even notice it.

Answer 3

ESXI virtualization overhead is about 15% plus or minus 5.

Answer 4

How much is the difference in Windows OS performance between a physical machine and a virtual machine?

Depends on the situation and tasks. Maybe less than 1% may differ at times.
If you just do office work, you won't notice the difference.

Answer 5

Watching what you will do. Any server service, any office application, and indeed everything that does not work with graphics (with graphics there are asses of different sizes - from small and elegant to huge) - will work in such a way that it will not actually be noticeable.
