It's up to your OS to use memory as file system cache.  Depending 
on your OS you may need to tune something, see your OS tuning 
guides for details.

In nginx you may want to tune various buffer sizes if you have 
enough memory, e.g. output_buffers, proxy_buffers, fastcgi_buffers 
and so on.  This is not about file system cache, but may reduce 
disk load if properly tuned for your typical use pattern.
