All aspects of the system affect processing speed.

Ultimately though, a networked systems is constrained by the speed of
data on a copper wire or fibre optic cable and thats capped by physics.

How much of the networking isn't fibre these days? How much that isn't won't
be by 2018? Compare 4G wireless data speeds with earlier generations. Copper
is just so passé.
