I have an FWSM module broken into several contexts and interfaces, it seems that whenever I push 500-550Mbit through it that it starts to create latency in the 100 times normal range for connections as simple as a ping. I saw a reference on cisco hints of a possible limitation in this area although I've been told it's 6 Gbit. I saw on the presentation of the FWSM module this can be lowered to 2 Gbit if the payload is small. Can anyone provide me a more clear picture of its limitations and how to handle them? Any ideas on what might be causing this?
