It is an easy derivative/proxy for the system level effect is all.
Bandwidth for updates (inter and intra system) are another choking
point but folks tend to be even less aware of those than cpu.

is bandwidth the only consideration?  number of graph nodes and
number of advertised endpoints and churn rate per endpoint don't
enter into the limits? at what system size does speed of light begin
to enter into the equation?

Right.  What is the computational complexity of the current algorithm?
