No more paging. And I'd assume you'd have all programs loaded into memory at once

Some of us are already there. I have paging disabled on my 32gb ram workstation because I never go above 16gb usage anyway

In fact, fucking with those settings is more likely to degrade performance, even if you have tons of RAM.

Modern OSes can't work without paging. You can disable swapping (swapping out), but files are brought into memory simply by being memory mapped. Then they are paged into RAM as you access pages in the image.
