to get a feel of memory usage, top isn't too appropriate, better use 'free'.  
it will show three lines: mem, -/+ buffers, and swap.  the first one is the 
same that top shows: total, used, free, shared, buffers and cached. the last 
one is for virtual mem, but the second one (-/+ buffers) is more interesting; 
it simply adds the 'freeable' ram (buffers+cached) to the 'free' column, and 
substracts it from the 'used' column.  so it shows the really committed 
memory.
