I guess in my case, the load average is general 0.00, but that is just
measuring userland activity no ? Is there a way to allocate more CPU to
the kernel for routing ? The box in question has some 100,000 routes, so I
dont think I can implement fast_forwarding-- or am I thinking of something
else?
Also, will removing ipv6 from the kernel make it more efficient acting as a
router ?
Thanks very much for your input.
