Why it isn't going to gig - dunno.
Yes, Its also not my main concern, I guess, with a different card, I'd also get the full 155MBit like I get with Linux in this case. I was just curious if someone knows why this card doesn't make GigaBit on OpenBSD, therefore appended dmesg...

OK, I got it, forgetting about calomel.org. At least with older OpenBSD releases, there were the recvspace, and sendspace to tune the buffers used for the networking. Especially for the high bandwith and high latency case, they improved things for me in the past. So when I understand you right, there are no knobs anymore I can tune? Also the FAQ: http://www.openbsd.org/faq/faq6.html#Tuning says, it should not be necessary for most of the cases, as it states: VERY FEW people will need to adjust any networking parameters! But since with Linux, I get about 1MB/s more throughput on the overseas connection. Since the FAQ did not stated, there are no knobs, I was hoping there might be something I can tune for my use case? If someone can say for sure, there is no knob I can tune, then I'll take it as is. If there is someone who could explain, why its slower on OpenBSD, so that I could understand what the problem is, then I'd like to hear about it, and I'd be happy. Well, not as happy as if I would be able to get the same throughput from the OpenBSD box ;) thanks, Sebastian > > -- > Henning Brauer, h...@bsws.de, henn...@openbsd.org > BS Web Services, http://bsws.de, Full-Service ISP > Secure Hosting, Mail and DNS Services.
