Oscar,
Generally, the PIX is a dedicated appliance that does one thing - firewall.
Therefore it is optimized to do that one job and do it well. Large
corporations/businesses could have hundreds (thousands) of users going
through the firewall to the internet - PIX (the right size of course) will
handle this type of traffic load without much effort.
The IOS Firewall Feature Set - which is now called "Cisco Secure Integrated
Software" (CSIS), is working along with the normal duties that the router is
doing. Therefore you may have to add more memory and things may slow down a
bit (or really slow down) the more users you have going through it.
However, CSIS also has some Integrated intrusion detection system (IDS)
capabilities built in - but again you're adding more overhead to the router.
So, size does matter. Small offices could probably use CSIS without much
problem. Larger organizations should look at the PIX.
