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. -- = ------------------------------------------------------------------------ Emmanuel Florac | Direction technique | Intellique | | +33 1 78 94 84 02 ------------------------------------------------------------------------ _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
