Have you tried iostat from sysstat to see the number of IO-operations performed per second (tps) on the devices when it is performing badly? If the number is hitting your seek rate (ie. 1/0.0075 for 7.5 ms seek = 133), then fragmentation is sure to be blamed. -- _____________________________________________________________________ / __// /__ ____ __ http://www.modeemi.fi/~flux/\ \ / /_ / // // /\ \/ / \ / /_/ /_/ \___/ /_/\_\@modeemi.fi \/ -- 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
