+Since wantarray context is basically the same as looping over $rs->create(...) 
+you won't see any performance benefits and in this case the method is more for
+convenience. Void context sends the column information directly to storage
+using <DBI>s bulk insert method. So the performance will be much better for 
+storages that support this method.
+
+Because of this difference in the way void context inserts rows into your 
+database you need to note how this will effect any loaded components that
+override or augment insert.  For example if you are using a component such 
+as L<DBIx::Class::UUIDColumns> to populate your primary keys you MUST use 
+wantarray context if you want the PKs automatically created.
