pix performance

what is the performance of PIX 535 & 525 for a 64 byte packet size? The stated 1.7 Gbps for PIX 535 & 370 Mbps for PIX 525 relates to what packet size ( 1518 bytes or less?). is there a document showing packet size vs. performance for these firewalls?

Re: pix performance

The numbers are measured using 1518 bytes because large packets provide the most attractive numbers for firewalls. Cisco does not publish any other numbers. I've seen other vendors compare firewalls to the Pix using UDP packets of different sizes.

Of course, even those numbers aren't achievable in a production environment as you'll have more than one host talking, TCP states to maintain, more than one process running, etc. If you really need to sustain more than a couple hundred megabits consistently, I would look at the 535 or a hardware solution like the FW blade in the 6500s. Also, Netscreen has some screaming hardware firewalls. [ sorry cisco ;) ]
