Thanks for the link. When I looked at it, the PPS and bandwidth didn't
really match what I see on my network so I'm curious to see what people
are actually seeing. It looks like their test is done using very small
packets (64K). Our traffic is mostly web with a lot of Video (netflix ,
Hulu, youtube, Flash etc) so we're dealing with a lot less packets that
are much larger. Based on the numbers I posted, we' would be at the BW
limit without even coming close the PPS limit (if we were running the
traffic through the 7206).
