So I am not sure that adding CPUs would be any better than the Linux

100 CPUs each with their own DRAM and some kind of communications
link between them. That sounds even messier.
If each CPU gets only its own part of the table, it doesn't have to
talk to the other CPUs that handle other parts of the table at all;
the only thing it needs is a way to update the FIB for that part of
Of course this is much harder to do that a single CPU implementation,
but once again: you don't want to optimize for stuff that happens on
human timescales (programming) at the expense of what happens at FIB
or even RIB processing timescales.
