Need more ram?

While there are some page outs, it's ony 2% of page ins. When page outs get above 10% that's a pointer to more memory being needed (note the values reset when you reboot).

That said, 2GB of memory, while the minimum for Mountain Lion and Lion, many have found that 4GB is required for performance.

I would definitely bump to 4GB.

No prob, it's not a huge deal. But it would likely be a bit snappier with some more RAM. Take a look at Crucial.com, tell it what machine you have and see what memory options it give you. You can probably do it for under $35 if you look around.

4GB (2 x 2GB) should run you around $25-$30. I would just do that and reevaluate the performance. That may be enough, especially on a new system.

I agree, just getting to 4GB should make a big difference.
