My router (with Wireguard) can't handle more than 45Mbit/s through Wireguard because the CPU starts throttling.

I suspect that RaspberryPi or old Intel NUC also would not be able to handle speeds anywhere near gigabit.

My NUC easily pegs the network. I'm not sure you're right about this. Either way: you can just use WireGuard as a control channel, the same way this software does.
