ROCK ON, brotha ... A Mac Pro at my work I put in 8GB. W00t. Running OS X Leopard Server it goes from anywhere between 6GB free to 0GB (as in no green part but still running smooth, etc.) when serving NetBoot/ NetInstall.
That's when the system borrows the HDD memory when it uses all the available RAM during a process. System performance suffers greatly.
Usually I'll start an encode before going to bed and will do a little surfing on the net. Since encoding takes such a long time, I let it finish while I'm sleeping. Often all I have open is HB and safari/camino. I will usually only have about 10 tabs or less open in the browser.
If you are having a lot ?of page outs during use then you should think about getting more RAM. I only seem to get them while encoding video with handbrake.
Just to add. I used to hack on Unix systems and when I effed up and had a huge memory leak the system would pound the disk writing stuff in memory to the harddrive. That's when I used the kill -9 commmand.
It's called a "pageout" because memory in Unix is organized in "page"s (chunks of memory). A "pageout" is when a page is written to the disk and then that memory is used for other stuff that's needed. When your RAM is used up and then the unused data in RAM will get "paged out". The problem is that it's slow and if you're trying to do it all then you need all the pages.

I've 2 gigs of ram in my MBP. I rarely get page outs. But I do seem to get them while encoding video with Handbrake. Is this to be expected?
can u explain what page outs are?

I wonder what a pageout is like on the MBA?
