Which already showed in [00/10], I paste them here:

        domU(orig)      4 queues        8 queues        16 queues
iops:        690k       1024k(+30%)         800k        750k


After patch 9 and 10:
        domU(orig)      4 queues        8 queues        16 queues
iops:        690k       1600k(+100%)       1450k        1320k
