|So I am not sure that adding CPUs would be any better than the Linux
|server situation of 2 or so fast CPUs with caches with a common
|DRAM.  I am not sure how suitable the BGP implementation would be to
|100 CPUs each with their own DRAM and some kind of communications
|link between them.  That sounds even messier.


Several BGP implementors have discussed it.  It's decidedly not pretty.
While it's not impossible, it's again a step up in costs and complexity.
