I think that instead of giving the CPU percentage, you should give the CPU time used: CPU time used = CPU percentage * total time This would give a more accurate measure of how much CPU is used by the different filesystems. As someone said, if certain operations are faster with reiser4, you expect a greater percentage of CPU time to be spent in the disk driver etc. - if the amount of I/O is the same, that is. Another interesting statistic would be the number of blocks read and written during the test. -- Jamie - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
