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 Fr33d0m4All
