Don't forget string handling. C/C++ handle strings significantly faster than Java, and this is generally what one would expect to find in an application who's domain involves parsing XML. One other thing does perplex me. I would have expected I/O bound behaviour to level Java and C/C++ rather increase the disparity. I'd be interested to know the details.
