Hi Thomas,

Thank you for running a relay!

Right now, Tor sees a lot of circuit creation requests due to what most
people think is a botnet that is using Tor.

The second issue is that Tor does not scale well across multiple CPU
cores yet. Looks like, either way, you are hitting the limit of your CPU
core.

MaxOnionQueue should not be necessary or helpful to set in modern Tor
releases.

If you see a maxed out CPU core, what you might want to try is run
multiple Tor processes in parallel. We do that, although usually for
modern CPUs this is only necessary at and above roughly 100 Mbit/s.
