amazing to still see

Each filter takes some CPU cycles. And CPU-Power is still really
expensive on a Cisco device.
A word stolen from the IBM world: "You will never have
performance problems. You may habe financial problems, but you
will never have performance problems."
a simple search on google, I find a paper
about a routing table lookup algorithm, on standard CPU,
able to do 30Millions lookup per second (on a 500MHz cpu).
with current CPU frequency, it would rather be 120Millions/s
on such "commodity pc" the bottleneck is the bus architecture, though.
2Gbit/s of traffic translate to roughly 400000 packets per second
that leaves a lot of spare cpu time.
