Well, for awhile now I've been curious as to how OS X handles memory. I remember reading something awhile back that said if you notice a lot of page outs in Activity Monitor that you need more RAM. Well, I got 2GB today and installed it into my MacBook, thinking this would take care of the page outs. While running iCal, Mail, iTunes, and Safari my page outs are appearing again. Is it something to really worry about? Also, I figured the extra 1GB of RAM would help Parallels but so far it hasn't. While using Vista, Parallels crawls at times even though I've allocated 1GB of RAM to it. Is this just more of a limitation of my MacBook? Thanks for any answers or info!
