Running Wireguard on a desktop might be roughly three times faster than OpenVPN (maybe), but I have yet to see a consumer router that can achieve a that kind of improvement, at best it seems to approach double the speed. Still impressive, but not the same.
Just to double check and confirm the above, so the best WG VPN speeds on todays routers (Ie Asus top end ones)
You could see roughly 400Mbps speeds?
