Hi all!
In release for last XCP (1.0.0) I've read that developers made caching
mechanism more efficient (caching VDI from network storage to local
storage). After this I have 2 questions:
1. How can I control it and measure it's efficient?
2. How this mechanism works? Does it cache full VDI? Or it caches the
most useful part of VDI p.e. running OS and its own cache?

I've read presentation for caching in XCP, but there were no
information about mechanism.
Best regards, Den.
