Summary

We are in need of a faster Gateway. While our current Gateway (a Intel Pentium J4205 has an average passmark of 2442 (918 single) is more than powerful enough for our gigabit connection;

just a single wireguard connection can easily spike the CPU usage to around 70%.

We also want a smaller case (1U) so that we can have more space left in the rack.

Notes

an 11th gen Intel i3-1115G4 could easily do wireguard at ~2GB/s so ideally we want to get a system just as powerful or more powerful.
one option would be to move wireguard to Erratic instead, however that means that a remote reboot of Erratic will kill all connections.
Right now we have an UniFi Dream Machine Pro on loan to test if we like it.
CPUs are compared using cpubenchmark.net, cpus should be faster than what we have now.

Options

Bkhd 1U Server Intel Atom Quad Core C3558 6 Lan 2 Sfp + 10G

Comes in a 1U case, can be figured with either a 4-core Intel C3558 (2417 passmark, 852 single) or a 8-core Intel C3758 (4750 passmark, 868 single). Has 6 lan ports and two SFP ports. See also https://www.youtube.com/watch?v=a3EMMYTdOYo

According to the Youtube video it idles around 20w and would spike up to 25w under load. (4-core version)

pros

Comes as a 1U case
Seems to come with a 12v Meanwell PSU build-in
Lots of lan ports
Has two SFP ports
The 8-core is about twice as fast as our J4205

cons

Slower than than our J4205 single core wise.
The 4-core version is slower
China, so support could be icky (though we are a hackerspace)
No video out, only console.
