    Can someone explain how to read the Activity Monitor? Please. I noticed the used on the bottom left of the attached pic says 3.76 GB. I'm running only Safari and iTunes and I'm using 3.76 GB of my 4 GB RAM? I guess 4 GB RAM is still not enough to run more than two apps? Thanks for any reply.

    You absolutely need more RAM.

    When your page outs are more than 10% of your page ins, that means you are in need of more RAM.

    You have a gigazillion tabs opened at once, or what??

    Not necessarily. First, page outs are cumulative since the last reboot. It's possible that at some point since the last reboot, the OP had enough running to cause page outs, but that may not represent normal use. Also, swap used won't go back to zero until a reboot.

    OP: restart your Mac and then monitor your page outs and swap used under normal usage.

    Is it running slow for you? If not then I wouldn't worry too much about it. I just checked my Activity Monitor and it says all of my RAM is in use, but I don't notice any slowdown.

    That doesn't show that it's all in use. You have 1GB not being used. Read the link I posted in the 2nd post to learn what Inactive RAM is.

    This is the best rule of thumb I've ever heard concerning RAM

    Why? There's no logic to this. You will always have page ins. You will only have page outs during times of greater demands on memory, which may be infrequent for a user's normal situation. There is no correlation between the amount of page outs vs page ins. A better rule is that if you have significant page outs under normal day-to-day use, you may need more RAM.

    No, it's not running slow. I was just curious that I'm only running only Safari and Itunes, and I'm reading the activity as being used to almost full 4 GB RAM. Just curious that's all. Thanks everybody for all the replies. Still learning.
