I have been starting to utilize deduplication on some systems in my environment running Windows Server 2012 R2. So far it has been working very well. My question I seem to have trouble ultimately figuring out is: Is it worth the trade off on the hit to cache? From what I understand when the dedupe process runs it would potentially cause all of those files to be cached. I would hate to see the cache unnecessarily impacted. Does anyone have any real world experience with that? I am looking mostly at user shares where I know there are lots of duplicate files and such.
