    # Cache open file descriptors, their sizes and mtime
    # information on existence of directories
    # file lookup error such as "file not found", "no read permission" and so on
    #
    # Pros: nginx can immediately begin sending data when a popular file is requested
    # and will also immediately send a 404 if a file doesn't exist, and so on
    #
    # Cons: The server will NOT react immediately to changes on file system
    # which may be undesirable
    #
    # Config: inactive files are released from the cache after 20 seconds
    # whereas active (recently requested) files are re-validated every 30 seconds
    # File descriptors will NOT be cached unless they are used at least twice in 20s (inactive)
    #
    # A maximum of the 1000 most recently used file descriptors will be cached at any time
    #
    # Production servers with stable file collections will definitely want to enable the cache
