Linus Nordberg and I wrote a short paper that was presented at FOCI 2023. The topic is how to use all the available CPU capacity of a server running a Tor relay.
This is how the Snowflake bridges are set up. It might also be useful for anyone running a relay that is bottleneck on the CPU. If you have ever run multiple relays on one IP address for better scaling (if you are one of the relay operators affected by the recent AuthDirMaxServersPerAddr change), you might want to experiment with this setup. The difference is that all the instances of Tor have the same relay fingerprint, so they operate like one big relay instead of many small relays.
The workshop presentation video (22 minutes) of this paper has just become available on YouTube. The paper homepage has a copy of the video too.
