JAXB 2.0 perfromance
I did some JAXB2.0 performance testing. In my result, if there is a single namespace in a XML file. JAXB2.0 Performance (marshall/unmarshall) is better than that of JAXB1.0. If there are more than one namespace in a XML documents, then JAXB 2.0 performance is worse. The reason for that is that I can use below option:
to optimize different namespace to share same runtime lib. when I generate java bean from a XML schema with JAXB1.0.
JAXB2.0 removes the option -runtime and I don't have clue to optimize it.
