RE: perf #s for GRF vs 7500 Re: Anyone Deployed Ascend's GRF IP S witch?

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.
