Ideally, you should have very little "free" memory according to top
(most systems will see under 20MB free). Free memory is wasted memory.
Unix uses memory not allocated to processes for a disk cache. To
determine whether you are truly low on memory, run iostat and watch the
swap columns. Constant swap activity means you're low on memory.
