VM and page faults

Question

VM and page faults

After installing MenuMeters to keep an eye on memory and CPU usage I noticed that it also reported paging. After an uptime of 6 hrs I have a reading of almost 3 million page faults...

Though I've used various Macs during the past ten years, I am fairly new to Mac OS X and memory managment in particular. I'm a bit worried by the amount of page faults. Should I be? What could be the cause and how do I find it, and more important how could I fix it...?

FWIW:I have my mini running 24/7, without sleeping. My user account is a standard, not admin.

It probably wouldn't hurt to max out the RAM. That's usually the cause of the pageouts I've seen.

Templeton Peck,

Thank you for your response. Maybe I should have mentioned in my original post that the number of page faults is increasing when the mini is idle. Even if I don't open any applications. The half of my memory is free at that time, I think there is something else causing the increasing faults.

Hello JJ.

Check Problems from Insufficient RAM and Free Hard Disk Space under Memory management in Mac OS X.

PAGE FAULT CITY!!!! My new dual processor G5 has been up, BUT sleeping most of the time for at least 4 days now. My page fault count is currently in excess of 36 million!!!! I didn't add any ram to the system, so it has the stock 512 megs. After reading about this online, I guess i'm getting these faults b/c of a lack of ram?!?! is 512 really not enough?!

I wish I could administrate VM and adjust it like I used to be able to in os 9/8/7
