I was wondering, in high performance environments (high compute loads, high bandwith loads(IB)), is it a concern to run a firewall for network performance reasons? Also, with high compute loads, I heard/read a rumor that a firewall might actually cap traffic?
Depending on the rules (SPI needs much more resources than stateless) and the traffic, there will be an impact. I can feel that effect on the Cisco SPI firewall in my C886va if I use it on links that have high traffic.
If you need a firewall, you need to provide enough resources to run it properly without a performance import.
