Performance issue with FOP

[Yatin Soni]

Hi,

    I am using FOP for the PDF generation in our project and For creating the 
xml source I am using the DOMSource model.Now at the 
time of transforming the XML document into PDF CPU usage rises to 99% and not 
getting down. Every time I am generating PDF I am 
facing same problem and this causes low performance at Server side. Please help 
me out resolving this issue. How I can reduce the CPU
usage?

Following code is used for the FOP:

    OutputStream out = new FileOutputStream(tempFile);
    out = new BufferedOutputStream(out);
    FOUserAgent foUserAgent = fopFactory.newFOUserAgent();
    Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, foUserAgent, out);
    TransformerFactory transformerFactory = TransformerFactory.newInstance();
    Transformer transformer = transformerFactory.newTransformer();
    Source source = new DOMSource(document);
    Result result = new SAXResult(fop.getDefaultHandler());
    transformer.transform(source, result);

I am new to FOP so please help me resolving this issue... 

Thanks,
Yatin Soni
