performance with/without dmcrypt OSD

Hello,
Any one ran with and without dmcrypt OSD performance tests?
For ex: I plan to build a ceph cluster with 1 PB raw size. and also plan to
use dmcrypt for all OSD. Can you please clarify, if this dmcrypt will
reduce/impact the ceph clsuter perofmrance?

Thanks
Swami

We have several clusters in the PB range that use dmcrypt.  I can't speak to what it's performance detriment is to a non-dmcrypt cluster, but our clusters run just fine.  I don't really understand the question though... Either you need dmcrypt for legal reasons in your business or you don't.  If you don't then why use it?
