Thanks for the tip and the numbers! People here are still a bit reluctant to 
run 2.4.x kernels on production machines, how is it working for you other 
than the gigabit/tcp stuff? I am running on dual p3 800s on one machine, but
have the card in a 32-bit PCI slot which I would guess could make a 
difference :)

Anyway, thanks for the info,
