@ConcernedOfTunbridgeWells @Phil I don't think this part is true: "The virtual memory is generally in the form of memory map files taken from disk. So this introduces a 48 bit limit for the maximum size of an application. Within CentOS that is 256TB, under Windows 192TB. The point really is that memory mappings are not limited to main memory size."
Windows virtual memory management isn't based on "memory mapped files taken from disk," so I'm not sure what that part was supposed to mean
I guess the author is saying it could be paged out, or something. But Windows does have a 48-bit (256 TB) address space now (though each process only sees 2 TB of virt address space AFAIK), so not sure whether the 192 TB limit would be coming from.
