O'reilly benchnarking XML parsers

O'reilly published results on XML parser benchmarks that they did:

Quote: "Our intention was to find the right components for our high performance web service security gateway, so that it could be run on a small dedicated appliance. The limited resources of such a device brought the C tests into the game, since the Java virtual machine already needs a lot of memory. Object model parsers are the most important parser types in the context of web service security because they can be used to alter a XML document in memory."
