On Web throughput, since so many TCP connections are involved?
The Web is actually a major source of the problem. It was not very well
designed, protocol-wise. It causes rapid transient congestion.
How big a problem is HTTP's opening of so many TCP connections?
It is a terrible problem. There is no time for the congestion and round
trip estimation algorithms to kick in, as each connection is so short.
But, HTTP is being fixed.
