    I have a MacBook Pro with 2GB of RAM. The system seems to use up all 2gb of ram pretty easily. Is this common? Also, am I having too many pageouts?

    Code:

    In my experience, with a normal program load (which you appear to have), OSX will leave approximately 25-33% of your RAM free, which is what you have. So yes, it's normal.

    But don't worry. That 648MB of inactive RAM you've got is RAM that was in use at some point, but isn't now, and the OS can reclaim it any time if it needs more memory. Add that to your free RAM and you've got over half of your memory available to the OS for new tasks.

    I don't know if your pageout number is high or not. On my 1GB MBP, I've got zero. But then, your machine had been running for four days when you took that snapshot, so I don't know.

    Don't know, probably not -- the uptime distorts the number.

    Need to restart and run a normal cycle to see.

    Loading a bunch of apps and swapping apps like a rabid monkey, will also distort the number -- since the background apps "may" be spun out to the HD.

    A second or two delay to bring an app to the front isn't a problem, as long as you aren't getting hammered while using that app.

    Do you put your computer to sleep at all? That adds quite a few page outs. Try it out. Check your page outs, put the computer to sleep, wake it up, and check your page outs again.

    I put it to sleep all the time! I guess I just got worried when I openned Activity Monitor and so little of my pie graph was green.

    Don't even worry about how the OS allocates memory, since it is likely to do a better job at it than you.

    You can probably mess with the settings, but you might be reloading the OS if you do. ;)

    If you see a lot of spinning balls while in an app, or a bunch of pageouts during a single session -- worry.

    But since it is a notebook 2GB of memory is about it, until the new 965GM chipset arrives -- next year. Then you may be able to bump the 965 machines to 4GB or 8GB.

    If you need more, buy a Mac Pro which has a 32GB limit right now.
