how much traffic does an unthrottled middleman draw on 100 MBit/s?

shrek2 is unthrottled, and the CPU and memory footprint is in
low 2-10%, while the network throughput is around 3-5% 
of a 100 MBit line (the switch has a Java applet which
displays traffic bar over the ports). It doesn't seem to be getting any more 
lately.

Does it take a long time until the server gets more traffic?
I'd rather not go away on a long weekend, and come back to 4 days
worth of full 100 MBit/s pipe.

So the total hardcoded limit is 9 MByte/s?

Any Tor people here who're with Hetzner? It's supposed to be
a reasonably good connectivity; I wonder whether this is propaganda,
or they have Tor traffic shaping in their routers.
