[sheepdog-users] Is qemu faster than sbd?

Hi experts,
I mounted sbd as ext4 and tested IOPS for 4k rand/seq rw
32 sheep, 3-replica. Backend is ssd.
The result is much slower than testing on bear ssd.randread IOPS: 16732randwrite IOPS: 1436sequential read throughput: 64MB/ssequential write throughput: 6MB/s
I saw some qemu fio test results from COJ2015 presentation, which is much better.
Is my sbd performance result solid? Or maybe it's configuration difference?
