I used to have a very big relay (sadly because of my provider not
anymore, but planning on reopening it).
The reason for doing this is to make use of all your available
bandwidth, because for the biggest part (resource wise) Tor still is
bound to a single CPU.
In such a scenario I'd also recommend to make sure AES-NI is on. Check
both that the kernel module is loaded and that OpenSSL supports it -
also maybe use the latest OpenSSL/LibreSSL, especially if you don't run
a recent release of your BSD. There have been improvements on ECC
crypto, making it possible to improve your throughput in somewhat recent
releases. Also if I remember correctly those were or still are disabled
Anyway, I think it would probably be a good idea to transform the port a
bit. Modifying the rc.d-script could be enough to have an option that
has multiple instances.
An example to take some ideas from would be the uwsgi port, which allows
you to have uwsgi_profiles, while still defaulting to a basic
uwsgi_enable with one instance.
I am not sure if that's the best approach, but I think this would make
things easier for people running a relay.
