Performance issues with XML data source

Katerina

Hello,

I am using Birt 2.5.1 and Tomcat. I have created some reports that get their input data from an XML Data source. The XML data are created during runtime and are sent to the report using a ByteArrayInputStream.

But I have very big performance issues...
Rendering reports with the XML data written in an xml file takes less than a minute when I use the Preview tab in the Eclipse BIRT designer and then I can export it to pdf within seconds. But when I feed the same data to the Report Engine as an InputStream from my application, it takes more than 10 minutes for the pdf to be created!

Most of my reports contain simple bar charts. I noticed that the chart creation is really slow, with each chart taking several seconds to be created. But I have similar performance issues with reports that do not contain any charts.

Do you have any idea why the performance is so low? How can I improve it?

I found similar posts in the forum, but none of the proposed solutions seemed to be related to my problem.

Thanks in advance.
Katerina
