So this is why 114 Tor exit nodes are apparently operating from Potwin,
Kansas! Figured it was a digital artifact. The article doesn't mention
Tor itself, but the nominal fount really jumps out on TorFlow.

Hi,
I've just moved my Tor relay installation from my alix1.c embedded
system (500Mhz CPU with 256Mb ram) which was able to offer only 4Mbps
(100% CPU utilization) to a new Raspberry Pi3 (quad-core 1.2Ghz 64-bit
cpu with 1 GB ram). Some days ago I've seen some messages on the ML
about Pi2 performance (if I remember well) and I'd like to share my
first experiences with Pi3. I have only 20Mbps connection in the
uplink direction, so I'm offering about 15Mbps for Tor relay and I've
just seen that it is able to offer 14Mbps with 40% of a single core
utilization.. In conclusion, I think that a single relay on Pi3 can
offer about 30-40 Mbps, and if you run 4 tor relays on the same Pi3
you can offer more than 100Mbps which is definitely not bad for such a
small system. The only drawback is that you need to find a good way
for keeping it cold, since after 1 hour of 1 core at 100% I've reached
about 70?C with heatsinks on the CPU.
I just wanted to share my experience with you, hope you find it
interesting :)
Have a nice week

If you build tor against OpenSSL 1.1 on that target you will get a
massive increase in performance due to support for the ARMv8 hardware
AES acceleration.
This requires 0.2.8.x from the maint-028 branch (or master if you're
brave) since I recently fixed tor (again) to compile with this version
of the library, but the changes will be in the next 0.2.8 release
candidate.

To follow up on your experience
I am currently running a relay from a rasp3 with a bandwidth limit of 24
Mb/s.
I am using the tor package from raspbian (Tor 0.2.5.12).
arm currently gives me the following informations:
cpu: usually between 20.0% and 40%
mem: 160 MB (17.3%)
for a current average down and up of 35.3 Mb/sec and 36.1 Mb/sec (due to
my high burst rating I suppose)
The 15 mins load average of the raspy (which mostly runs tor) is 0.38.
It may be biased by me running arm, which seems rather CPU intensive, to
look things up for a while.
I am not monitoring the temperature. The CPU seems a little hot to the
touch, but not overly so. The rasp has an uptime of 14 days.
All in all it seems to handle the load rather well!
Regards,
