I remember it was 30 kbyte/s.

I think the layer-2 tunnel would carry the "worst" traffic. I have also done 
some measurements in the Vienna network to determine how many packages of a 
certain type are going around and got ~500 packages/second... someone has set 
REALLY insane timing settings into OLSR, but the next release will contain 
code to allow slower timings without fear for longterm routing loops.
