Should I install Win Ser 2012 on bare metal or on VMWare?

Question

PHP

There is Dell PE R210-II (Xeon E3-1240V2, 2x2TB SATA 7200 (combined in raid 1), RAM 4 GB). Introduced as storage for the "My Documents" folder of 60 AD 2003 users (terminal server and AD server are two other machines). That is, Dell's task is only to store (well, process) user files.
I can’t decide: put Windows on bare metal or still install VMWare ESXi and roll Windows onto it, allocating 2GB of RAM to it, and leave the rest of the memory for deployment in the future of some other virtual machine that does not require a lot of resources.
How much, in general, does the performance of a virtual machine on VMWare fall on average, compared to the same machine, but on bare metal?

Answer 1

Do it by analogy

Answer 2

The drop in performance for VMWare is about 5% (but this is my IMHO, and my own observations). Slightly worse for XEN. The fall is strongly felt when using HV.
It all depends on what component what load. If memory and percent are given to the virtual machine with practically no overhead, then here is the network and, worse, the disks are given through a tangible layer.
It is more difficult to administer a "clean" server if there is no IPMI \ iLo nearby. Well, you don’t have enough memory to directly “have fun” with virtualization. I don't think the game is worth the candle.

I recommend the free absolutely hyper-v server 2012r2. Without gui, but Windows on Windows virtualization works much better. The image can be found in msdn, the installation is familiar. Admin via powershell. The beauty.
Unless other versions of guest OSes are planned, of course. Although Linux already feels quite good on hyper vi.
