none I have noticed as of now. The data is not copied inside the bonding driver, it's just "assigned" an interface, so that is very fast with a very low overhead.

in active-backup mode or in load-balancing ? If you want to use LB, be careful about the choice of algorithms, and avoid round-robin as much as you can, as it de-sequences packets. This can increase memory and CPU usage on the receiver. However, XOR and ALB are generally fine. You really need to experiment, though.
