Having spot-checked some of your longer-running requests, they're all getattrs or setattrs contending on files in what look to be shared cache and php libraries. These cover a range from ~40 milliseconds to ~150 milliseconds. I'd look into what your split applications are sharing across those spaces. On the up side for Ceph, >80% of your requests take "0" milliseconds and ~95% of them take less than 2 milliseconds. Hurray, it's not ridiculously slow most of the time. :) -Greg -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
