thanks @enealDC and @To-M.

One more question: I've seen documentation indicating the a bonded interface will not provide for better performance with replication. I understand that a bond only multiplies bandwidth for multiple connections; does each replication task not create a new connection? Am I going to see better performance with 7x jobs across 2x Gbe or should I get 1x 10 Gbe inteface to speed this up?

TIA
Dave
