Hello all!
      I work with processor: MIPS 4KC.
      I check network performance without iptables & conntrac enabled
      and it has near 80Mbit/s.
      When I enable (without adding rules) network performance was
      near 40Mbit/s.
      While testing ksoftirqd is get near 50% of cpu. And (it is so
      strange) top eats the same! However cpu has 100% load and
      perfomance is real bad.
      Has anybody same problem?

I mistype: with iptables&conntrack perfomance only 30Mbit/s

Just loading the connection tracking module will pull networking
performance into a deep hole, no surprise there.  All your numbers are on
the low side though.  What clock rate is your CPU running?
