Hi all！ I am testing rbd performance based on kernel rbd dirver, when I compared the result of the kernel 3.13.6 with 3.18.11, my head gets so confused.
look at the result, down by a third. 3.13.6 IOPS 3.18.11 IOPS 4KB seq read 97169 23714 4KB seq write 10110 3177 4KB rand read 7589 4565 4KB rand write 10497 2307 thanks for any help！
