I don't want to be too harsh, but, I feel it is time to tell you that you are a bloated piece of crap.
Why does a freaking browser need over 500 Megs of memory to run? You are a web browser, not a CAD program.
Needing that amount of memory of course leads to the need for page faults. Hey, all programs do it. It's not just you. But over 300 million of them? In two days? That's just wrong.
Honey, you need to lose some weight.
