according to this free chapter of Tomcat: The Definitive Guide, Second Edition book http://oreilly.com/catalog/9780596101060/chapter/index.html tomcat's JIO (old plain java connector) outperforms apache httpd in nearly all tests, so don't bother playing with APR:) > Since Tomcat's request processing is all in Java (right?), the request > must first be processed by Java, including creating all those objects > that are included in the request.

Well, actually when it comes to IO performance Java outperforms C, so I wouldn't place my money on old bets like C is faster because its C.
