:However whats interesting is DF performance in the fileio/seqrd benchmark
:with one thread. DF seems to be about 4 times slower. But when you add 2nd
:thread it almost catches up with FBSD.

    What parameters to sysbench are you using and is the data set being
    tested large enough to blow out the system caches?
