Many, especially within an enterprise or between cooperating
enterprises, or where the carrier offers VC circuits as a product.

You've missed the point. If the streams need to go to different places,
or need different QoS parameters, or for any other reason need to be
independent of each other, then separate connections are needed.
Multiplexing multiple streams into one TCP connection is a Bad Idea,
quite apart from the processing complexity that it introduces.

Processor speed has little to do with it.
