I just performed a dedup simulation on my box and this is what I got:
I get that there is a possibility of having 1.31 dedup ratio if I activate it... right?
Now, the box is a i3 4130 (3.4 ghz) with 16 gb RAM (Of course ECC RAM) and 8 TB on a mirrorred raid0 setup (4 x 4TB disks) and no more than 3 concurrent clients connecting to it: Clients that are actually people working from their Mac Pros storing data and retrieving it from time to time. I also have a jail plugin with crashplan running on it in order to upload my files to crashplan servers.
I sincerely think the gain vs the usage the server has makes activating this worth it but I'd like a second opinion from experts :)
Thanks!
