I'm trying to understand the "cleartext throughput" term that Cisco uses in their performance specifications of the PIX-525. The PIX can be expanded to up to three gig-ethernet interfaces but it is listed as being capable of handling only up to 330Mbps. That sounds like it can't even handle one gigabit interface let alone three. A guy at Cisco TAC said it's 330Mbps per interface although he wasn't able to produce any documentation to support his statement. Even that is still well below what the interfaces could throw at the PIX if they were pretty busy. Am I missing something or is the box just underpowered relative to what traffic could potentially need to pass through it?
