OpenVPN has both terrible configuration and performance compared to just about anything else. I've seen it really drop off to next to no usage both in companies and for personal use over the past few years as wireguard based solutions have replaced it.
Same here. With openvpn my somewhat modern cpu takes out a whole core @100% at like 200 megabits/s.
With WireGuard I instead max out the internet bandwidth (400 megabits/s) with like 20% cpu usage if that.
I really don’t understand why. We have AES acceleration. AES-NI can easily do more bps… why is openvpn so slow?
