    Resolution: Won't Fix

Resolving per the Xalan-J JIRA meeting April 5, 2005. Resolving as "Won't Fix". Significant 
performance work has gone in since 2.4.0, but not
enough for issue reporter. The testcase provided by Andreas Felix may yet be useful in the future. However we no longer consider this issue active.

> We use Xalan in the Version 2.4.1 for a Search-Engine(Web-Application). The 
> database is Oracle 8.1.7 und the Web Server runs on HP-Ux with Apache and 
> Tomcat. using Java Servlet with Java Version 1.2.2 .The Content from the 
> Database (XML) is transformed in HTML with XSL´s. With multiple concurrent 
> transformation (about 200 users on 1 machine, different stylesheets) the 
> transformation times are getting higher and pushes the performance down.
> Code-Snippet:
> Result pOut = null;
> TransformerFactory myFactory = new TransformerFactory.newInstance();
> // Prepare XSL-Transformer
> StreamSource xslSource= new StreamSource(new File(myStylesheet));
> Transformer myTransformer = myFactory.newTransformer(xslSource);
> // Prepare XML
> // String xmldata
> InputStream xmlInputStream = new ByteArrayInputStream(xmlData.getBytes));
> InputStream xmlIn= new BufferedInputStream(xmlInputStream);
> StreamSource xmlSource= new StreamSource(xmlIn);
> // Transformation
> myTransformer.transform(xmlSource, pOut);
> // Code-Snippet-End
> Have anybody related problems?
> Are the usage of Templates better for the Transformation process?
> deeply gratefule for any advice!
> thanks to the community!
