    Description

      The order of properties in SyncData has an impact on indexing performance on the server - xattrs are processed in order until the property referenced by the index is found.

      The revtree (history) section of our metadata can grow large under some scenarios, but isn't referenced by any of our indexes.  Moving it to the end of the marshalled sync metadata will reduce the work on the indexer side.
