do you have any numbers on that? because i don't see it.
Even my old Pentium4 route servers do very nicely with that.
And look at the processing power of the Route Engines of the 
hardware routers... wow are they slow! 

So, where does this come from? 
Will there be a break even point where current CPUs won't handle that anymore?

My bigger problem with that actually is FORWARDING, not route calculation.
The only reason i have hardware routers with ASICS is the wirespeed throughput,
they still all have low-end CPU route engines for route calculation....

(But yes, slower CPUs == bringing up a BGP session takes 20min or so, we know that)

And unfortunately i just now notices that this drifts a bit off topic.
