While I have not tested it yet the 2 email chains I have seen from users trying it is that the performance has been worse rather than any increased benefit. Perhaps those using it successfully are just quiet and haven't responded when others had issues.

Let's assume a storage with tiering and sharding enabled, used for
hosting VM images.
Each shard is subject to tiering, thus the most frequent part of the
VM would be cached on the SSD, allowing better performance.
Is this correct?
To put it simple, very simple, let's assume a webserver VM, with the
following directory structure:
/home/user1/public_html
/home/user2/public_html
both are stored on 2 different shards (i'm semplyfing).
/home/user1/public_html has much more visits than user2.
Would that shard cached on hot tier allowing faster access by the webserver?
