I can assure you: You are not referencing more than two million different memory pages (each 4 kibyte) all the time!

Yes, you are. That is the problem. Not exactly all time, but in a minute you may need to reference 30 millions of pages. The OS will have to swap pages a lot. You have running Java virtual machine, .NET, ARM emulator, an editor with has in memory all the methods and variables and modules, so it can prompt you parameters or suggest properties. You have the debugger running. You have a browser, each page with its images, with page rendered in memory to display it fast, running the javascript machine, with the DOM of the page, plus plugins, etc etc. Software is more bloated day by day, so every application/program/service pretends that you have 4Gb of RAM. You operating system is thus emulating a 200 Gb machine and it is continuously swapping pages.

If you really are banging your head into the ceiling at 8 GByte, it sounds as if paging is turned off on your machine.

No, I'm sure he hasn't turned off paging. No modern software can run without paging. I don't think that a standard windows 10 installation can boot without paging. Simply the system is slow because software uses a lot of memory and it swaps pages lot. He clicks on window, the OS dumps all memory associated to the current window and loads the memory associated to the new active window because it has the whole physical RAM used, and that takes a few milliseconds. Finally every gesture means swapping, so applications don't run, creep.
