Improving multi-core support can allow users to saturate high bandwidth connections with cheaper processors, less setup, and just more efficient deployment of high-capacity nodes in general. Improving multi-core support should be a major priority.

Sure but I doubt anyone contests that it's better to have multicore support, than to not have it. However that work doesn't get automatically done.

One quick and simple stop-gap alternative that I suggested some time ago would be to stop ignoring more than two relays per IP address.

With the IPv4 shortage and abundance of multi-core CPUs, raising that limit to let's say 4, would at least allow many people to run a Tor process per core on the same single IPv4 that they have (utilizing up to four cores, not just two).

This was suggested in https://trac.torproject.org/projects/tor/ticket/13414

But the concern was that any increase to 2 relays per IP would make it much easier for sybil attacks. Perhaps we could try an increase to 3 or 4 per IP?
