Activity Monitor - Should I increase RAM?

[MacBook08]

I'm not sure if this is cause for concern but it seems like my "free" memory has been really low as of late. I use Safari and Mail 90% of the time. The other 10% is occasional iTunes use, MPlayer use, and Preview use. Is it time for me to upgrade to 4 GB of RAM?

Note - I do use the following extensions in Safari: AdBlock and YouTube5.

Your Page Outs (the real indicator) is not too high. If this is indicative of normal use for you, you might get a slight improvement with more RAM, but it's doubtful. There's more to it than just Free Memory:

Not really, as "Inactive" memory is kind of free too and becomes available if needed.

with you usage no, but should your usage needs expands i would suggest so as you would soon run out of memory.

For Safari and Mail, 2GB should be enough. Your Safari is a little fat in real memory. You should take a look at virtual memory usage, because is in the HD and can slow down your system. I got a MacMini with 2,5GB running Adobe stuffs, Apache, etc. and it is working.

There is some softs that free up memory by clearing caches, but it is also effective the control over small and numerous little software like iTunesHelper that "eat" a lot of resources - do you really need it?
