How well does this perform with UDP traffic?

Assuming this tool results in two peers connected over WireGuard (no relay server), the UDP performance should be great. Probably fine with a relay server too but I can't say definitively.

Good answer! Wiretrustee uses kernel Wireguard if available, therefore the performance is the same as plain Wireguard.

There are some caveats though. We use a fixed mtu value of 1280 to be on a safe side while wg-quick dynamically detects the best value. We will improve it.

If the Wireguard kernel module isn't available (true for older Linux, Mac and Windows) then userspace implementation is used (wireguard-go) which is slower.
