> This article published [0] on April 2010, shows that Axis2 has some major performance issues compared to Metro and CXF.  An analysis suggested that most of the problems were with the axiom-dom module's methods, along with Rampart. So, first we went on improving the axiom-dom module. Here's a patch for the improvements we did.
> Final assessments suggest considerable level improvement.  Graphs for a sample run of requests with small and large samples will be added to the files section.
