I've been trying to figure out what the desired ratio of page ins/page outs one should have as I've been told that determines if you will need to get more RAM or not. The almighty internet seems to have a few thoughts on this, and as I don't know the answer myself, I was wondering if anyone knew which one of the recommendations I've researched is correct. Thanks!
Suggestion 1: No page outs. If you start to have page outs at all, get more RAM. You shouldn't be having page outs at all.
Suggestion 2: Page outs should be less than 5% page ins. If your page outs are 5% or less than your page ins, you're okay. More than 5%, get more RAM.
Suggestion 3: Page outs should be less than 20% page ins. If your page outs are 20% or less than your page ins, you're okay. More than 20%, get more RAM.
Suggestion 4: Don't worry about page ins and page outs. That's just technical stuff. If you notice your computer running slower, get more RAM.
Which one of these is a good way to determine if more RAM is needed? These were all suggestions I found trying to research it on Google, and I don't know if there's a right answer or not for this?
My page ins are ~ 40,000 and page outs ~ 30 for having a few applications running at the same time (Firefox, iTunes, downloading stuff, iPhoto).
