nice statistics. I can not provide stats of my own, as I don't run
Dragonfly yet, so I'm more of a hypothetical user right now. But one
thing that's of interest to me is how long did the de-dupe process take?
I ran them one by one. at my own pace but the biggest two
simultaneously did not take more than 2 hrs.
So I guess 2-3 hrs would be a nice approximation :-)
My experiences were different on a file system containing a lot of data
I didn't try dedup itself but a dedup-simulate already ran for more than
two days (consuming a lot of memory in the process) before I finally
So yes, dedup seems to run fine but in my experience doesn't yet scale
very well to larger amounts of data.
