Something's wrong with the file create/stat/delete tests. Did you mount
with "nobarrier"? 
Which drives, controller firmware, raid level, stripe width? 

BTW don't run only one test, it's meaningless. I always run at least 8
cycles (and up to 30 or 40 cycles) and then calculate the average and
standard deviation, because one test among a cycle may vary wildly for
some reason. You don't need the "char" tests, that doesn't correspond
to any real-life usage pattern. Better run bonnie with the -f option,
and -x with some large enough value.
