Hi! IMHO this test is not 100% correct. ext3 | data=writeback ext4 | data=writeback,extents,delalloc xfs | defaults is ordered ! So you have compared ext's in writeback (which fastest mode) vs xfs in ordered. - To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
