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.
