About having a relay on gigabit symmetrical FTTH, you don't just need a
good server, you also need a good NAT router unless you want to use your
server as a NAT router as well.
I don't have Sonic or Gigabit Fiber (from any ISP), but I have 300mbps
symmetrical Verizon FiOS in Brooklyn, NY running a Tor middle relay. A
Linksys running OpenWrt and many low-power Mini PC "firewall" boxes were
a bottleneck even on 300 Mbps for Tor, despite having a powerful Xeon
4108 HPE ProLiant ML110 Gen10 and having no Verizon router in my setup.
I dabbled with using my ML110 as a PF firewall (I run FreeBSD), but
yesterday, I installed a HP ProDesk 400 G4 as an OPNsense firewall
(because I didn't want a single point of failure, and so I can remotely
access iLO).
So your firewall needs to be more powerful than an average one because
at least for me Tor has ~10000 connections at once, and that is with Tor
only measuring half my 300Mbps. Your Gigabit will mean far more than
that running Tor. So a low power HP T620 Plus or Qotom box won't work as
a firewall in this case.
My "bottleneck" could also be Verizon's peering that Sonic may not have.
After all, Sonic supports Net Neutrality and Verizon opposes NN.
About the server, I have a powerful HPE ProLiant as mentioned earlier,
but like other said at minimum you need a i5/i7 CPU, or an equivalent
Xeon or AMD CPU. So this means no NUCs or HPE MicroServers.

Hi!
I have Sonic Fiber which offers gigabit symmetric connection. I am
thinking of using it for gigabit Tor relay, but I wonder what would be
good hardware to use for something like that. Information I have found
[1] is from 2010 so I wonder if there are any updates? Is there any
simple small box I could use? Like Intel NUC? Information here [2]
says that one can get 400 Mbps with AES-NI. And so with two processes
limit per my public IP this would be around 800 Mbps then. Is this
still a reasonable expectation? Do I have to care about the network
card to serve gigabit (besides its being nominally gigabit)? What
would be memory requirements for such a device?
