    aio with directio is still work in progress which can be tracked here
    This needs to be fixed in the fuse kernel module itself.  I think this
is what you were
     looking at perhaps.

    Well disable-direct-io can be done away as since 2.6.26 fuse kernel
module supports
    big_writes which even with disabling direct io you get good performance.
