OpenVPN is quite configurable, not as much as IPsec, but still a lot, and (from what I hear) has quite a bit of code bloat. I believe that userspace WireGuard has better performance than OpenVPN.

My understanding (and experience) is that OpenVPN on windows is structurally capped at about 5-10 MB/s. I was curious of how that compares to WireGuard.

Performance issues with OpenVPN on Windows arise out of the inefficiencies of the TUN/TAP driver, not the OpenVPN software itself.

I am sure that's true, but unless there is an alternative driver I am not sure why that makes a difference.
