>pentalty for stopping traffic (by congestion) for 10ms is 10ms delay.
That's because Ethernet has flow control, while car traffic doesn't. That's why my example was about a very fast switch with no flow control or collision detection. Basically, a fast but otherwise terrible hub.
We can't solve the inherent problems of hubs by making them faster, but somehow we think it's okay to solve inherent problems of bad road design by adding more lanes or increasing speed limits.
