Extremely high ‘Page ins’ number

[HighEndMac]

I have done some research on ‘Page ins’ & ‘Page outs’ and from what I can gather having a high ‘Page outs’ number is a sign you need more RAM. However I have not found much on ‘Page ins’.

I have a very high ‘Page ins’ number, usually in the high 100,000s (like 690,884) Can anyone tell me what this means? Is it bad or good, what’s the deal? Thanks

page in's are fine. your computer wouldn't even work if it didn't. basically its just the HD moving things into ram for usage.

You will always have Page Ins. You don't need to track the amount. Like Page Outs, they are cumulative since your last restart.

It's the Page Outs you need to keep an eye on.

But either way, just do a restart when you head to for some coffee...

Thanks for the feedback, i just thought it was strange to have 0 page outs and 1.7Mil page ins.

It's not strange at all. You could have many GBs of page ins and zero page outs. Page outs only occur when you've exceeded your available physical RAM. If you have sufficient RAM, you may never see page outs.
