Rob, Comparing your BAY routers to everyone elses is like comparing a top fuel dragster to someones 69 Chevelle street racer. You folks have some heavily modified software and hardware, from what I understand. However, we've got a couple of BAY BCN/BLN routers about, and the numbers that have been mentioned previously in this thread are fairly accurate.

Folks, We have bcn/bln's out there with over 60 bgp peers on a 64Mb ARE. Works fine. Taking in about 63000 pps (170 Mbps) over 6 interfaces with a high of 20k pps when I looked a couple of minutes ago..Not untypical of the 30 bcn's and bln's on our network.. So the 4-6 Mb per peer thing is inaccurate. On the way high side.
