The answer, Boris, is that the "team" has no idea what they're doing. Check out some of the threads on performance testing. They tune little pieces here and there, and break 10 other things in the process. Matt Dillon "determined" that 10,000 ints/second was "optimal". Of course if you're passing 10Kpps that means you get an interrupt for every packet.
They're playing pin the tail on the donkey.

Unfortunately that's a not so uncommon result with em and 5.3. There are tuning methods but they won't give the big kick.
Like mentioned, try 5.4 (BETA1), depending on your employment you'll see tremendous improvement, I don't have values handy nor can I confirm that for amd64, but you really wnat to try out, especially if this box isn't productive yet, which it isn't if I understood correctly.
I am running 5.4-Pre now. Its the same. Everyone always say try new version, but it always the same.
i compare em to em, only difference is amd64 vs i386. So amd64 O/S is this much slower than i386? So why anyone use? Is like nobody know what is going on with this OS. Before, people tell me Opteron on i386 no good. But now that I test, its much better than amd64. Why is there always excuse with FreeBSD 5? Always try next version. Always same slow result?
