Sorry, this is on the target (Isilon FS). Locally (on a F21 workstation and ext4 FS) it clocks in at 154G and 159G respectively.

This means that the size of a single file is probably 16K, rather than the typical 4K desktop file size. However, I do not have files that are that small where it would make a difference. So, I don't know. I see: the dedupe is supposed to run over weekends but I am not sure what it does.
