Well, it's the same for rbd, what's your stripe count set to? For a small system, it should be at least the # of nodes in your system. As systems get larger, there's limited returns... I would imagine there would be some OSD caching advantage to keeping the number limited (IE: more requests of the same device = more likely the device has the next stripe unit prefetched).
