I'm a little surprised that this kind of question is not documented anywhere, or at least I have not been able to find it. I have only found others asking the same question as me without getting a good answer. There was a quite exhaustive discussion seven years ago: https://lists.torproject.org/pipermail/tor-relays/2010-August/000164.html This one got closed before a good answer: https://tor.stackexchange.com/questions/9966/system-requirements-of-tor-rela... I am prepared to pay a pile of cash for a computer that I will dedicate to run a relay. I have a 100 Mbit/s symmetric connection. What should I buy? I don't want to buy something that has a too slow CPU that is not able to push enough traffic, but I also don't want to overkill and get a huge electricity bill. Sebastian, How much CPU does your relay have/use? ________________________________ From: tor-relays <tor-relays-bounces@lists.torproject.org> on behalf of Sebastian Hoffmann <sebastian@machinewithoutbrain.de> Sent: 17 March 2017 12:39 To: tor-relays@lists.torproject.org Subject: Re: [tor-relays] What kind of hardware do I need for my relay Hi Farid, I'm running my Guard / Relay on a VPS with only one core and 512MB RAM. Its also hosting a blog, my own mailserver and is member of pool.ntp.org I haven't encountered any problems so far. It's also connected via 100MBit/sec You can see the stats here: https://atlas.torproject.org/#details/F381D6294A93A0078B76D0DCA332133CF5C8F6... I experimented a bit in the last weeks with being a bridge, but I now I'm back as a Relay... therefore the performance charts are not as high as they have been at the end of last year.

I haven't looked at computer hardware for a long time. What is the cheapest and most power efficient CPU/motherboard that can saturate 100 Mbit/s as a Tor relay?
