Hi Daniel,

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)

Cheers
