2 hops on full duplex links I'm getting 464Mbps. There is some loss at each hop and I'm not sure why. Could be virtualbox and resource contension that isn't showing up in task manager and/or top on the vm's. is this to be expected? On Sat, Aug 19, 2017 at 12:25 PM, dan

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

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?
