Thanks for all the answers. I'm currently going down the path of looking at
IPtables' conntrack slowing the forwarding rate.
If I can't find any more docs then I'll boot the router with a kernel
without any IPtables built-in and see if that's it.
As Lee said "rollback" ! That's the last change to the box. If I can rule
out the logging of traffic from conntrack is slowing down
the forwarding then I can look into hardware further ;-)
