A few hints to consider:
Linux always try to use the whole RAM available, free RAM is useless  
after all. So nearly all RAM not used by applications/kernel/network  
buffers is used as filesystem cache as needed. In your case the most  
is in the fs-cache and Swap is not used at all, so you don't have a  
RAM shortage/performance problem related to RAM.
