I'm using nginx to serve files cached by merb. Passenger/mod_rails to deals with requests not served by the cache. merb is not touched by the test case here. all test (cached) files are handled by nginx or passenger.<div>
<br></div><div>Nginx can serve a cached file ~5,000 / sec. That drops to 5 / sec when "passenger_enabled on." Please see the notes in the body of the server block of the nginx.conf below. Anyone know the cause of this drop?</div>
