That sounds like you are able to push more than that after tweaking? My
CPU usage is okay now (around 50-70%), but I am still unable to push
more than an average of 200 Mbit/s per direction, with a maximum of 240
Mbit/s. Judging from the Torstatus page, yours don't perform much better?

Only Blutmagie seems to be able to push more, which suggests that
- there is a bottleneck in Tor
or
- there is indeed not more demand for Tor traffic on the ports we allow
or
- there aren't enough middle nodes?
