The use of RFC 2544-esque metrics for firewall performance testing mostly benefits ill-informed or unscrupulous firewall marketeers, who send 1500-byte UDP packets and then brag about excellent performance. For firewalls handling TCP traffic, upper-layer traffic metrics such as HTTP object size, concurrent connection capacity, and connection setup rate are a lot more meaningful. The RFC 2544/2889 approach is OK if you only ever use your firewall as a router or a switch. The performance of a firewall used as an L2-L7 device should be measured with L2-L7 traffic. dn
