That's the idea, but every device is different, and they are very complex. Especially for write performance, tuning is a long and complex process...a simple benchmark run where you do three tries and average them isn't going to give you a great picture of drive performance. -chris -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
