These virtual machines are on a strict memory diet Smile I have configured all three to have 32mb available RAM but on dynamic memory.

With no user logged-in and with only default services running, here are the results:

We see that the Windows Server 2016 Core installation runs at 454 MB next to it is the GUI for 2016 then finally at 692 MB for 2012 R2.

*Launches 3 Visual Studio 2015 and creates 3 web performance test projects*

I want you to draw your own conclusions based on the data that I have shown in this blog. I also wanted to publish the Load Test Results, but thats for another time. Until then, see ya!
