Thats > quite a little router you have there! lol. I have to recognize that I didn't follow the thread very carefuly and I propbably missed some posts. I just wanted to say that when using freebsd as a pure router using intel cards, polling realy helps. I've noticed 10-20% CPU utilization decrease with polling enabled. Second, I didn't mean 150Megabytes/sec, rather Megabits/sec. Third the actual CPU load is ranging from 0-4% (according to top), but with an average of 1%. And finally I just did a test and enabled polling on that box. The CPU idle state immediately dropped to 88% while interrupts increased to 10-12%. P.S Danial, have a look at this http://www.webopedia.com/TERM/M/Mbps.html -- Best regards, Cezar mailto:cezar@arax.md
