Httpserver performance

[robert engels]

It was done more out of curiosity. I know the code fairly well so I was surprised in the low performance of the JDK httpserver so I set about to figure out why.

As you probably know, the original motive for this HTTP server was something basic to support XML web services callbacks. Today it provides an on-ramp to web development with local testing. It's also useful for other testing too, or just to serve up API docs or other content. It's never been a goal to have it be competitive in either features or performances when compared to other HTTP servers. Just saying to explain why there hasn't been a interest on net-dev to add pipelining or other features.
