I noticed that the routing/NAT-performance is in FreeBSD noticeable higher than in OpenBSD. I think that is due to the SMP-support of pf in FreeBSD. I would point you to George Neville-Neil's and Jim Thompson's work, titled "Measure Twice, Code Once". They've presented at multiple conferences over the last two years, and you can find transcripts, slides and recordings via google. Google "george neville neil jim thompson measure twice code once" and you'll pretty much get all of their results on the front page. As mentioned by others, it's an active area of research and/or development (take your pick) in the OpenBSD kernel. FreeBSD traditionally focuses more on performance, whereas OpenBSD traditionally focuses more on correctness, security, and to some extent, elegance. In other words, your results are entirely normal. -Adam

I just won a bet (from a friend of mine) that this was going to turn into a troll. Thanks for the confirmation, dude! (My friend is not happy with you, though. ;)
Re: openbsd vs freebsd NAT performance

Somebody lied to you. There is no problem with OpenBSD, it is doing fine.

Several developers are actively working on the various parts of making the entire network stack capable of taking advantage of multiple CPUs. OpenBSD 5.9 has several improvements in this area (c.f. http://www.openbsd.org/59.html), but AFAIR packet processing in PF is still single-threaded. Philip Guenther

Please add some hardware description of your machine. > I think that is due to the SMP-support of pf in FreeBSD. Should be. As far as I know, pf is a real hungry beasts when it comes to multicore CPUs. But I think you didn't activate SMP pf support in OpenBSD, did you? > Is there also a SMP support (intended) in OpenBSD? Yes there is, still some things are in work.
openbsd vs freebsd NAT performance
Hi, beside OpenBSD 5.8 i installed FreeBSD 10.3 on my router-pc. For routing i use pf. I noticed that the routing/NAT-performance is in FreeBSD noticeable higher than in OpenBSD. I think that is due to the SMP-support of pf in FreeBSD. Is there also a SMP support (intended) in OpenBSD?
