The switch will probably be *slower* that the crossover. Depends on
which layer the switch operates and its modes of forwarding (cut
through, store and forward, etc). Basically a switch has to do work on
the packets to shuffle them around. A cross over cable doesn't. Its just
the two computers going hammer and tongs.

Of course theres collisions. But switch <-> Computer has collisions too.
Anyway. You'll find a switch slower (Its really trivial. Because they
are both really fast).
