Thanks. I am aware of that test but it is two years old and OpenBSD had quite a few optimisation in between. Hopefully we will have some update test from Phoenix again once FreeBSD 14 releases.
Indeed. There's been a lot of work towards unlocking the kernel and network stack (removing "big locks" that force code to run serially), so it would be cool to see some iperf tests on the same hardware with different OpenBSD versions.
