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.
