I need to get a slower test-router so I can benchmark properly :(

I need to get a very old pentium or high-end 486 with PCI.

I implemented this a while ago and then accidentally lost the sourcetree
but I did do some profiling which I can't find now :(

A similar thing was recently done in VFS in kernel 2.5 for the atime
updates and it gave a very nice speedup, I doubt the speedup will be as
large here since the timer handling is a lot faster than disk-io.

I'm currently in the process of going through the locking in conntrack
to try and make it more scalable (splitting ip_conntrack_lock) and
trying to fix things I find.

Never argue with an idiot. They drag you down to their level, then beat
you with experience.
