Hi Mihai, first I am not an openbsd guru. I am more an happy user like you.
I read of some other BSDs (DragonflyBSD, FreeBSD) that they bring more smp support into pf. https://www.openbsd.org/faq/pf/perf.html The nice FAQ told use that openbsd pf don't benefits much from smp. So I assume that's an more single thread processing for pf. I also guess that it is the "keep it simple and then more secure" idea behind that rules openbsd as main goal. It's not "the fastest OS on earth", they never told us that. The sad thing of all the forked smp pf versions is that they don't get it in openbsd. So the nice and new pf features lives in openbsd, nowhere else. Therfore I like openbsd over the other BSD for my use cases. And are you running in some issues? Therefore the issue can discuss and maybe solved. In the Apu2 thread @misc you see some people who runs maybe in single core limitations (the pcengines Apu2 runs AMD 1 GHz quad jaguar embedded CPU). It's the same direction.
