You will start to see error messages in your logs. It is very unlikely
that you will be able to satisy the interface with just one Tor process.
Best I've seen is 400 MBit/s per Tor process on modern machines with AES-NI.

How long did you leave your relay up and running? Let me quote from
Roger's recent great blog post:

"A new relay, assuming it is reliable and has plenty of bandwidth, goes
through four phases: the unmeasured phase (days 0-3) where it gets
roughly no use, the remote-measurement phase (days 3-8) where load
starts to increase, the ramp-up guard phase (days 8-68) where load
counterintuitively drops and then rises higher, and the steady-state
guard phase (days 68+)."

I have not tried such a thing, and I don't think anyone else has. It's
very easy to run and manage multiple Tor processes, and so far every ISP
was able to provide more than one IP.

Great effort, thanks! Please keep it up!
