The >| question is if the box is able to forward more then 150kpps. Yes that's one a the questions. We can divide it into 3 questions: 1) is the limitation comes from hardware ? 2) is the limitation comes from OpenBSD ? 3) is the limitation comes from the way OpenBSD exploit hardware. 1) Except if someone explain by a+b why the hardware can't forward this rate, I'm keep thinking it can do it (otherwise I don't see reason to sell quad 1Gbps nic). I'm ok to hear that I've purchased crappy motherboard card or nic (but I'd like to understand why they are crappy). The last 2 questions are still open in my mind. I've spent days and days making tests, searches, reading kernel source code and so on because I think it's interesting for the community to find where the problem come from and how to solve it (if possible). If finally the answer is that OpenBSD (or may be any other OS) can't forward more than 150kpps without losing 1 to 20 pps with this hardware, I'll live with it. But as we've already seen that increasing int/s improve performances (for good or bad reason), I keep thinking there's something to improve or fix but I may be wrong. Anyway, thank you for your work and help. Manuel -- ______________________________________________________________________ Manuel Guesdon - OXYMIUM
