That depends. The process of actually de-duping is some what intensive
depending on the process but if you clone off a template it's not and
you get other advantages like improved use of cache and less I/O on
the disk array so it's very dependent. I generally see more
improvement than loss. But that is getting off topic as if there's
less OS it uses less space whether it's de-duped or not and that is
not a bad thing.
