The slowdown of write thruput is on the raw raid, and on file systems without elevator algorithms. If you employ a file system with an elevator algorithm, then there will be no noticeable slowdown for writes, as witnessed by many benchmarks. best regards keld -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
