I'm only able to test in virtualbox at the moment.
I have a 3.1Ghz i5 and I'm able to do iperf across a batman-adv network (nodes A-B-C with A and C not directly connected).
iperf between a<>b is ~1Gbps, A<>C is ~560Mbps and B has 1 core hit 100% by ksoftirqd.
So it looks like I'm stuck in a single thread.
I'm going to add a 4th node and do a double hop A<>D iperf and see what happens. full duplex interfaces here so I don't think I'll see a big drop in the next test.

Anyone done any performance testing over wired links? ie, if two ethernet ports are gigabit and are added to bat0, what kind of throughput is expected across these interfaces and how much CPU is needed to get up near wire-speed?
