Doing a streaming read in 10MB chunks when RBD is striped over 4MB objects won't be terribly efficient. You should get the best sync read performance when the object sizes match up. You'll get better performance if whatever is sitting above the block layer dispatches multiple read requests in parallel (i.e. something smarter than dd, like a file system). sage -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
