Re: tuning for high connection rates

Enable polling on the interface and see if that helps. See man polling.

We tried polling already and it didn't help at all.

As I understand it, and correct me if I'm wrong, polling helps against
high interrupt rates but for that intel gigabit cards have interrupt
moderation. We don't have a problem with interrupts (20% CPU) at the
moment but with system (100% CPU) as you can see in the system
monitoring graphs. Interrupts sometimes peak at, but usually are under,
the 2k interrupts/sec limit.
