[B.A.T.M.A.N.] iperf in 3 node batman-adv network

Hi all,

I am implementing the 3 node batman-adv network.

A <---> B <---> C

B is the relay point for communication between A and C.

I have setup the batman-adv 2011.1.0 in all nodes and succesfully I can communicate and also use avahi between all nodes.

Now I want to calculate bandwidth, jitter and throughput patterns.

To calculate bandwidth, I used iperf -s on machine A.

On machine B, I used iperf -C <ip address of A> This gave me a bandwidth of 89.1 Mbits/sec

On machine C, I used iperf -c <ip address of A> This gave me a bandwith of 89.0 Mbits/sec

Since, there is relay through B to reach C, I was expecting the bandwith from A to C to be less around half (say 50 Mbits/sec). Is my understanding correct?

Please help me.
