Interesting, but OpenVPN can be configured in many many ways, whereas Wireguard can do fairly little in comparison (even though it does its things remarkably well).

Needless to say, the way you configure OpenVPN affects its performance.

So I would like to ask, how did you configure OpenVPN?

Did you use DCO (https://openvpn.net/as-docs/openvpn-data-channel-offload.htm...) ?
