Even a 1,8 ghz Atom can max out a 100mbit line … you don't need much …

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:

This one got closed before a good answer:

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?

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/F381D6294A93A0078B76D0DCA332133CF5C8F687 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.

Hello,

I have been running low powered middle relays for a few years.

Now I think it's time for a small upgrade.

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?

Thanks.
