Yes, 0.56(.1) has a significant performance increase compared to 0.48
Two blogposts which might be interesting to read:
* http://ceph.com/dev-notes/whats-new-in-the-land-of-osd/
* http://ceph.com/uncategorized/argonaut-vs-bobtail-performance-preview/
I'm not running with HDFS, but I see a good performance increase with
Virtual Machines running on RBD.
