Ouch.  I haven't met a vendor that made a product that could stand up to
the bandwidth very well.... except for Juniper.  I guess that ~200mb/s is
reasonable for a gig card. My guess would be the only reason why they came
out with this is because you can buy gig cards for linux and 
solaris.  More of a marketing thing really.  How many free PCI slots on a
nokia?  mb/pci slot might be another reason.

Well, the way I have always looked at it is, an over powered firewall
will likely have better latencies, less jitter, and less packet loss when
dealing with reasonable speeds.  Then again, I have never done a
"normal" firewall install.  Most people don't care too much about these
things... it seems.  I guess that people don't put firewalls between their
engineers and accounting.... so all you ever deal with is internet
connection.  A T1 or something.  Not Fast Ethernet.... or worse.

I did ask Checkpoint over and over again about which network card they
used in linux... or what rule base they used... I don't remember now if I
ever got an answer.
