How can the speed of the virtual RAM
Lots of things have timeouts. If paging is sloowwwwww, some things time out at 30 seconds or less. Software is confused. Lockups, Crashes. On one project with a smaller older notebook, stuff crashed at 2 GB, ran slow and rarely crashed at 4 GB, and ran at full speed with more than 4 GB.

One use of memory is for the file cache. I found with SSD, the file cache was not so important as the OS could reread file info fast. On magnetic disk, rereading stuff that was pushed out of the limited file cache was too slow and resulted in applications locking up. In that case, the files were big, images, 10 MB, and video, 100 MB. I never see that when working with code files which are mostly less than 10 KB.
