dedup is an extremely new feature in ZFS and not even enabled in the

source code for it is in the open source version (Oracle hasn't been 
releasing new source code to much of anything) or B) its considered 
stable yet.

frankly, the only place I'd consider using any sort of dedup is in a 
backup system like backuppc, where its implemented at an application 
level rather than transparently in the file system.  as your file system 
object count grows, it becomes astronomically more expensive.
