However with RBD the image is spread across thousands of objects across the entire cluster. At the end, you get way more performance by using RBD since you intensively use the entire cluster, with the object solution you only request one big object from a single machine so you get less performance. > It used to work like this, but since bobtail it's not true anymore.
