      Description

      With the new storage engines available in MongoDB 3.0, in order to switch from one storage engine you need to either mongodump/mongorestore or do an initial sync.

      Initial syncs copy collections and build indexes serially, which is incredibly slow. Like the new version of mongodump, initial syncs should be able to parallelize collections copies and index builds.
