Hey all, I have to admit to ignorance on this subject, never spent much time worrying about swap file and VM. Never much interested me.
But, for reading this discussion I have a question. I have 12M of Ram and 12M of Swap (could afford more only have 250M). Now if I have a program that requires 20M of Ram to run, then With my specs it should run? I'm I right on this one....?
