If you use the ASYNC I/O capabilities, which requires both libaio on Linux and the HornetQ
native code library, it opens the journal file(s) (for persitent messages) using the
direct I/O.
You probaby know what that means, but its the way HornetQ squeezes the most of our
persistent messaging performance and scalability, so its more than just native
asynchronous I/O.

Why is the direct filesystem access required ?
IMHO that's a typical usecase if the server is running in cloud
anyway.
