With this limit, they must have n/2 IPs at their disposal. For example, this paper[1] shows an attack for harvesting onion services. It would have been much easier without the 2-per-IP limit.

Note you need to specify separate data directories for each Tor process.

Hey, Tor process is only mono-cpu, so if you have RPi v2 or v3, the full quad core will not be used 100% by 1 Tor process. On this list I've already read it's possible to launch several Tor processes, so all cpu x4 cores can be used at same time. About hardware, I don't know if the RPi can go to 20Mbit with 1 process (or 4).

Re: [tor-relays] Cheapest HW to get 20Mbit?
Hi Daniel, Judging from my pi3 mid relay where 5mbit traffic is about 20% of 1 core (tor uses 1 core mostly) 20-25mbit should be fine for pi3. In the peak hours it will be probably close to maximum what pi3 is capable on 1 core but when cost is a factor I would not think of anything else 1gb ram is more than enough, my tor uses about 150mb If you think of exit, cpu load may be higher ___ tor-relays mailing list tor-relays@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-relays
