Maybe this article from the Tor FAQ will help: http://archives.seul.org/or/relays/Aug-2010/msg00034.html

According to the article, Tor can only get 100Mbps per CPU core, and Tor doesn't use any more than 2 cores because it's not fully multithreaded.

You can only run 2 instances of Tor on the same IP address, which means a maximum of 800Mbps, if you do it right.

The answer from this link is pretty straightforward on how to run multiple instances: https://stackoverflow.com/questions/14321214/how-to-run-multiple-tor-processes-at-once-with-different-exit-ips

Just make sure you correctly set the MyFamily option in torrc, otherwise a client could (unlikely but possibly) use both of your instances in the same circuit.

I am surprised as well because my middle relay has quite a low traffic,
at least not as much a I expect.

Advertised Bandwidth: 7.74 MB/s but it should do more

It is quite a small box but always has free memory left:

niehaus@rocket:~$ vmstat

The highes percentage of CPU use in top I have seen is about 15%, there
is quite a lot idle time left. AES is supported in hardware, network
speed is okay;

Anything I can do to donate more bandwith? Any more information you need?
