will adding more ram reduce the number of page faults?

simple yes or no question, but if you could explain why i would appreciate it.

i'm in the middle of an argument with somebody.

i'm under the impression that the more physical ram you have the less you will have to swap out to disk, meaning less page faults. then this guy chimes in and says "less page faults because of more ram? what are you talking about"

who is right?

thanks

It depends. If the page fault occured because the page is on the disk - you're right in most cases. But if it's in a different place in the memory, more RAM will not help.

Like he said. The argument is double sided... You both loose..
