How do I calculate the amount of free memory my system has at any given point in time?
What do you mean by "free memory"?
My top usually looks like this:
Mem: 72M Active, 668M Inact, 165M Wired, 29M Cache, 112M Buf, 70M Free Swap: 2048M Total, 5448K Used, 2043M Free
I understand the "70M Free" part, but should I add "668M Inact" to that? Or is it more complicated?
It's more complicated. The "inactive" memory refers to pages that have been used (but not recently), and thus are candidates for being replaced by more active pages, if the system has enough activity to want such pages for other tasks.
