Over 3GB of swap files with 16GB of RAM?

Just bought a MBPr with 16gb of RAM (more for futureproofing than any actual need right now). I'm constantly checking Activity Monitor and "Free RAM" is always around 8GB or more. I notice, however, that the "Swap used" totals are quite high. I don't have any pageouts so why do I have so much swapspace being consumed? With an SSD drive in here, should I not be worried that the OS is using swapspace so much when it probalby doesn't need to?

Thanks!

MacBook Pro (Retina, Mid 2012), OS X Mountain Lion

Virtual Box could still be the cause, try this: reboot, do not start VBox, give it an hour or so (doing whatever you normally do) and observe the swapfile, then add VBox to the mix and check again.

The cause is not related to virtual memory. The longer you persist in thinking that it is, the longer you will suffer from your slowdown.

For someone who claims to understand how vritual memory and swap space works, I don't think you really do...

I did mention that I had a problem with hanging right after waking from sleep. I guess you weren't paying attention.

You're fine, there have been no swaps to disk since you last started your Mac.

Make another user account, boot into it and test the Ram usage there.

Adding more Ram is cheap and simple, that is my recommendation.

If you use Chrome, you need another browser and possibly more Ram.
