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). Let's try ;)
Hi Since a few months back I have two RPi running Tor relays and delivering about 1Mbit each of peak throughput. Now my ISP has increased my max upload speed and I am looking to contribute more, somewhere in the 20Mbit range or possibly more.
But what hardware do I need? Has anyone written down a list of minimum requirements to get a certain throughout?
I have tried to google, but failed.
Sincerely Daniel Armyr.
