10.6: Completely Disable Virtual Memory in Snow Leopard (Lion in this case)
Authored by: Michelasso on Aug 06, '11 03:52:32AM

Ok, I have tried this hint in OS X Lion. I disabled the VM. After leaving the MB (3GB RAM) on overnight, surfing a couple of hours today I decided to re-enable it again. Well, it freed 300MB of RAM. Not sure were it took it from. Safari's processes have the same size and OS X created swap area of 50MB.

I tried this hint because in some HW OX Lion with Safari 5.1 fills large swap areas (1-3GB) even having plenty of inactive memory (>1GB out of 3GB total RAM in my case). I really would like to understand how virtual memory works in Lion because to me this doesn't make sense at all.
