Dear Ankit:

 I am not sure what your goal is.
Is it to increase available RAM by 'tuning' your system,
rather than by installing more RAM memory?
I think that 'top' will display running programs and
sort them by the memory they consume
 (or try to comsume).
What programs or services are installed in your setup
and how much memory are they consuming?
You probably need look no futher than the 'top ten'.
