Overall, I am astonished by the current furor over the attempt to get
better-perceived user performance. The Web has some design characteristics
which make good performance difficult. Namely, all the connection opening.

Overlapping i/o requests is a time-honored approach to improving performance.

On the other hand...

overlapping doesn't always help.

My eperience living on the end of a 14.4 modem suggests that MAYBE two
simultaneous transfers work well, but I don't think so. Certainly not
more.

The problem is that the congestion control mechanisms in TCP aren't
sufficiently sensitive to "coordinate" the consumption of such a small
pipe.
