Hey everyone. I manage an exit at a university, and I recently moved it to a gigabit connection. I did some tests and the machine does appear to be capable of fully using the available bandwidth. Besides getting two Tor instances to run side-by-side on the same IP, is there anything else I can do to further contribute the connection besides waiting and maintaining uptime? I set my average and burst bandwidth limits to the maximum upload speed I have been able to achieve in my tests, is that an ideal setting? Please advise.
Thanks.

You'll need to run multiple Tor instances on different IPs (two per IP) as the Tor code is not parallelized internally enough unfortunately.

Excellent! Thanks! :)

You need more than two. If your CPU supports AES-NI, you will roughly need one Tor process per 300-400 Mbps. If you don't have AES-NI, one CPU core (one Tor process) will be maxed out at around 100 Mbps.
Per 2 instances, you need one IP.

It takes some weeks for your relay to actually attract enough traffic. Monitor CPU usage closely, and limit bandwidth speed accordingly before you hit 100% CPU on one core (htop). Other than that, you can go as high as possible.

Oh, btw, you should also subscribe to https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-relays-universitie... , a list specifically for university relay operators (very low volume).
