Loosed Bindings
A collegue pointed me at the latest BindMark results. These guys are doing in-depth performance benchmarks on Java-to-XML binding for all the big players, as well as a few that I had never heard of.
Interestingly, JiBX (which does bytecode weaving) and Javolution are the clear performance winners, handily beating out JAXB, XMLBeans, Castor, and others.
