    I have 12GB of RAM and yet my Page Out counter is currently at 72.5MB after 1 Day 1 Hour hour of uptime.

    iMac 27" i3
    2x2GB + 2x4GB (NuRam)

    Win 7 VM at 2GB RAM
    Download and uncompressing large files through jDownloader
    VLC with 1080p and 720p movies
    Opera with > 10 tabs
    Some other apps like iCal, Things, Mail, Calc, iTunes

    Is this normal? I was expecting with 12GB of ram I won't be having any Page Outs.

    Don't worry about it, that's a minuscule amount of page out. There will usually be some page out after some usage even if you probably never filled up the RAM at any time.

    OS X also uses up RAM first, then slowly releases it. So that means that even though you have inactive RAM, OS X will page out instead of freeing it. It's just the way it does it.

    Like I said, unless you start getting GBs of page outs, don't worry.

    Thats a very small amount. After 8 days I have 98 page outs with 9.9GB ram.

    When the page outs get into the tens or hundreds of thousands, then you need more RAM.

    open terminal, type in "top". after "VM:", at the end of the line there is "x(y) pageouts". if y=0, you're ok.

    Thanks :) Wasn't expecting to have page outs with 12GB of RAM.

    @300D
    98 page outs? Do you mean 98mb ?

    @toxic
    Yeah it's 0, care to share what does that represent?

    @John T
    Hahaha I am enjoying my new com :D The iMac + Magic Trackpad combo brings simple day to day tasks so much more interesting.

    I don't understand it completely, but from what I understand the page out number you see in AM or before the () is virtual memory that's been allocated as a buffer. The number in the () is the actual amount that's being paged out.
