    Page outs are when your computer uses all of its RAM and it starts using the hard disk drive/SSD as RAM. Hard disk/SSD access is much slower than RAM, therefore your computer takes a performance hit.

    If you have adequate RAM, you shouldn't see many page outs. It is a good indicator if you need more RAM.
