You aren't showing the I/O size, only the latency. It looks like this is mostly sequential writes, since it's merging most of the I/O. Because you only assigned 1 volume (sdb), you will be limited to a single queue. I'd recommend adding more volumes and striping the data across.
Is adding more volumes, and stiping them in OS, better then using the RBD fancy striping options ?
