Nginx (to my knowledge) doesn't have such a facility, nor does it need
one. The VM system of the operating system you're using will cache oft
accessed data in memory, thus it won't always be read from disk.
So you're experiencing high disk IO with just static pages, the best
thing you can do in the short term is add more memory (which Memcache
would need otherwise anyway)
