BGP evaluation

[Sathya Perla <sperla () netplane com>]

Hi,
In general, how is a BGP implementation evaluated/benchmarked by an
operator? 

Are there any well-known figures relating to memory-consumption, speed of
convergence, scalability etc. that one can benchmark with?

There was a write-up on Data Comm magazine testing Juniper's M40 BGP. I
haven't seen much more than that - especially test procedures used to
compare various vendor implementations.

Thanks in advance,
