The linux file system will cache recently or frequently used files in
memory regardless, and the effect is similar in performance to an
application level cache. A separate application level cache would not
necessarily be desirable since the file system cache would largely
have the same items in it anyway; storing them again in an application
level memory cache would simply leave less total memory available to
file caching or other uses.
