For completeness sake, I upgraded my VM to 13.1 and ran my benchmark again. The slowdown of CLOCK_MONOTONIC compared to CLOCK_MONOTONIC_FAST is now only about 3 times.

Thanks for looking into Tor performance on FreeBSD. I'm seeing similar results on a physical ElectroBSD system based on FreeBSD 13.1. Some munin graphs and dmesg are available at: <https://www.fabiankeil.de/blog-surrogat/2022/06/22/clock_gettime-patch-fuer-tor-auf-electrobsd-getestet.html> Fabian
