      Description

      Full sync using mongo is VERY slow. The transfer rates obtained via multi-session rsync with compression are many times faster and could be indicative in where improvements could be made.

      As it stands, nodes will be in initial sync for excessive amounts of time on anything other than a moderate amount of data.
