It's a pretty big difference. 5meg for a sparse-root zone, maybe
100meg or more for a whole root. (Depending on what you run
that can make a huge difference. If you're running multi-gigabyte
java apps then it gets lost in the noise.)

I presume that zone clones get you quite a lot of the sharing back.
