Strange. This is not consistent with our measurements... you should be seeing much better performance. Questions: 1) What is the input? DOM? Stream? SAX events? 2) Are you using extensions? 3) Do you have a reproduceable case that we can feed through JProbe to see what is going on? 4) What is the output? > I got a compiler exception compiling my sources using Xalan 22 D13 !! Geez, I don't even know what this is about. Does anybody have a clue? > BTW : Is there a way I can identify a Xalan or Xerces version ? Which class(-member) is holding a release number ? > Is this number detailed enough to cover beta-versions as well ? See org.apache.xalan.processor.XSLProcessorVersion. It should have everything you need. -scott
