> I've detected that org.apache.axis2.databinding.utils.BeanUtil class can be improved for performance. It seems that invoking Introspector.getBeanInfo(Class, Class) takes a lot of time. By caching java.beans.BeanInfo in this class it doubles up (at least) the performance, especially when returning a big dataset. I changed this myself and saw a great deal of performance improvement.
