+ * significant performance improvements due to the superior threading and

+ * allowing the DB to be run on separate hardware
+ * allowing basic active/backup high-availability with a "hot spare" synapse
+   pointing at the same DB master, as well as enabling DB replication in

+The only disadvantage is that the code is relatively new as of April 2015 and
