Yup, as i said, which isn’t too bad (imho). “Real” LAG/LACP can’t provide 2x bandwidth for one stream either, can it?
The nice thing about balance-alb is that you don’t have to care (or forget, in my case) about how the switch is configured. Ever come across a switch that “someone else” has set up LAGs on but nobody can remember (or admit) why? )
Throw arpwatch on the bonded-NICs server and see how the bonded interface flips between the slave MACs as intended
