Virtual Memory under OSX?

[SDAVE]

I have 9GB of RAM...let's say I start Virtual DJ for testing purposes, and load a song on one deck. Under the Activity Monitor, it says 120MB of "Real RAM" in use and 426MB of "Virtual Memory" in use??? So it's STILL hitting my disk even though I have 9GB of RAM????

That's addressing space that has been allocated for virtual memory and not actual virtual memory in use.

So what does it mean? It's not hitting the disk?

Can I disable Virtual Memory? I am sure that I will never go above 9GB of use.

Right now, VM Size is: 10.46GB...Page In/Out is at 55524/0
Huh?

I wouldn't ever worry about virtual memory unless you're almost out of disk space.

You're not getting any Page Outs (pages to hard disk) either.

So I'm good?

I'm sure OSX is smart enough to do VM correctly.

Under Windows you had to manually enter a new amount if you ever added more RAM.

Or you can let Windows judge the amount...

You're fine.

Yes, you are fine. A page out is when a block of memory is moved from real RAM to the virtual memory files on disk. As Eidorian noted, this has not happened since your last reboot, so you are not using any virtual memory so far.

Thanks guys...don't know, OSX felt a little sluggish after I had 2 adobe Apps and 2 Apple apps open.

Were they PowerPC applications?

No, all are UB. I was running After Effects CS3, Photoshop CS3, Final Cut Pro 6 and Motion...maybe I am hallucinating.
