describes the problem: Websites do not provide one large tcp stream,
but many small ones, many of them with multiple tcp connection setups
and teardowns. Those are eating up the latency budget for a snappy
website.

There's a cute tool which allowes one to test it:

accurately measure client side performance of Web pages."
