      The new compact command has been optimized to be very fast at building several indexes during the compaction of a collection. Keys for all indexes are written to temporary files during a single scan of the collection data.

      The same technique could be applied to initial sync and would make it faster for big collections with several indexes. See the compact code - given that is now done it should be fairly easy to plug in to initial sync (clonecollection).
