But since April 2015 this automatic tuning got broken and has worsened significantly for some scenarios. The solution should be not that "well you're SOL and now always have to hand-tune it", but to keep reporting your experience and try out the proposed fixes so the prior automated adjustment is reimplemented, or baring that, to revert the behavior change on your systems (already tried that just now on my kernel build, it still reverts cleanly). -- With respect, Roman -- 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
