Re: Performance with large Tables
Results on my two-year old IBM ThinkPad X31 with a Pentium M 1.4GHz. Sun JDK 1.4.2_12, -Xmx128M, FOP Trunk: First run 11sec, subsequent runs 6.4sec. Sun JDK 1.5.0_07, -Xmx128M, FOP Trunk: First run 12.5sec, subsequent runs 6.1sec. Sun JDK 1.5.0_07, Server VM, -Xmx128M, FOP Trunk: First run 27sec, second run 7.2sec, subsequent runs 5.2sec. I don't have time right now to do any profiling but I still hope that helps you a little. Looks like you should check your memory settings and consider buying new hardware. :-) On 29.06.2006 22:18:48 mcevikce wrote: This is the link for the fo file. http://www.4shared.com/file/2278690/5364bc01 This file takes about 27sec in average to generate PDF.

Re: Performance with large Tables
Thank you for running the file. There is a huge difference between your
result 6.1 sec and mine 27 sec.
It would be awsome if I can get this to run on 6.1 sec.
Are you testing this from a command line using fop.bat? Can you tell me
which libraries are you using? Also any other information about the
environment you running will help. Here is my environment:
- jdk1.5.0_06
- Saxon 8.6
- Crimson
- I got the FOP trunk about 2 weeks ago.
- Running a webapp on JBoss 4.02.
- Servlet is making the call. Here is the code that makes the call. I belive
this is similar to what Fop.bat does.
private void transform(HttpServletRequest a_req, HttpServletResponse a_res,
String a_html) throws Exception {
TransformerFactory tfactory =
TransformerFactoryImpl.newInstance();
Transformer transformer = tfactory.newTransformer();
SAXParserFactory factory = SAXParserFactory.newInstance();
factory.setValidating(false);
factory.setNamespaceAware(false);
//BufferedOutputStream buffOutput = null;
ByteArrayOutputStream arrayOutput = null;
try {
if (System.getProperty(debug_mode) != null
System.getProperty(debug_mode).trim().equals(true)) {
Log.info(a_html);
}
StopWatch.setThreadEvent(PDF-transform-start1);
a_res.reset();
ByteArrayInputStream arrayInputStream = new
ByteArrayInputStream(
a_html.getBytes());
BufferedInputStream buffInput = new BufferedInputStream(
arrayInputStream, 1024 * 1500);
//buffOutput = new
BufferedOutputStream(a_res.getOutputStream());
arrayOutput = new ByteArrayOutputStream();
//buffOutput = new BufferedOutputStream(arrayOutput);
Map parameters = new HashMap();
String pagewith = (String)
a_req.getSession().getAttribute(
pagewitdh);
if (pagewith == null || pagewith.trim().equals()) {
Log.info(PDF will be generated with default
page with of 2000px);
pagewith = 2000;
}
parameters.put(pagewidth, pagewith + px);
XMLReader parser =
factory.newSAXParser().getXMLReader();
XMLFilter filter = new CSSToXSLFOFilter(null, null,
parameters, parser);
//Setup FOP
FopFactory fopFactory = FopFactory.newInstance();
Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF,
arrayOutput);
//Make sure the XSL transformation's result is piped
through to FOP
Result res = new SAXResult(fop.getDefaultHandler());
Source src = new SAXSource(filter,new
InputSource(buffInput));
StopWatch.setThreadEvent(PDF-transform-end-initialize1);
transformer.transform(src, res);
StopWatch.setThreadEvent(PDF-transform-end-convert1);
a_res.setContentType(application/pdf);
a_res.setContentLength(arrayOutput.size());
// Send content to Browser
a_res.getOutputStream().write(arrayOutput.toByteArray());
// Send content to Browser
StopWatch.setThreadEvent(PDF-transform-end-write1);
a_res.getOutputStream().flush();
//buffOutput.flush();
StopWatch.setThreadEvent(PDF-transform-end-flush1);
} catch (Exception e) {
e.printStackTrace(System.err);
} finally {

Possible memory leak
Jermias,
Thanks for the input. I'll try the XML - FO file - PDF approach, but my
initial tests show that the FO file gets created without any issues and I
suspect the FO - PDF conversion has issue.
Meanwhile, I was trying to get a little into the performance issue and I noticed
that the memory consumed by the java process almost spikes by 400-500 gig and
also seems that it does'nt get released after the transformation is completed.
This is how I base my observation :
The java batch process runs on a 2 CPU server which has about 8GB RAM. The heap
size was set to 1 gig. Before running the process, the java virtual memory was
showing around 600MB, and right after the FOP process started, the memory went
all the way up to 1.3 gig and stayed there. The process concatenates every 500
xml's into 1 PDF (the 500 XML's themseves are available as a concatenated XML).
I tried initially with 2000 XML's, which should have produced 4 PDF's. I enabled
Garbage collection on Websphere and kept track of it when the job ran. What I
saw was, the amount of memory GC was able to clear and make available was
getting reduced slowly say from 25% initially to all the way down to 0% and
eventually in the middle of the last PDF creation, the process got terminated.
Each of these XML's have tables and are about 2-3 pages in size. It also uses
barcode4j.
Below is the transformation code :
FopFactory fopFactory = getFopFactory();
private void transformXMLToPDF(FopFactory fopFactory, Source src, Source xslt,
File pdf, File foFile
throws FOPException, TransformerException, IOException
{
OutputStream out = new java.io.FileOutputStream(pdf);
out = new java.io.BufferedOutputStream(out);
try {
Fop fop = getFop(fopFactory, out);
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer(xslt);
transformer.setParameter(print-mode, true);
Result res = new SAXResult(fop.getDefaultHandler());
transformer.transform(src, res);
logger.im(Completed transformation!);
fop = null;
} finally {
out.close();
}
}
private FopFactory getFopFactory()
{
// configure fopFactory
return FopFactory.newInstance();
}
private synchronized Fop getFop(FopFactory fopFactory, OutputStream out) throws
FOPException
{
// configure foUserAgent
FOUserAgent foUserAgent = fopFactory.newFOUserAgent();
return (Fop)fopFactory.newFop(MimeConstants.MIME_PDF, foUserAgent, out);
}
I'm at FOP-0.92beta.
Please provide any suggestions. I'll work on the doing the process in 2 steps
and log my obervations.
Thanks
karthik

The memory allocated to the JVM by the OS is not a reliable indicator for Java memory leaks, JVM implementations tend to keep memory allocations (as does basically every program which is supposed to be used in general in a one-shot mode), A peak indicating that the whole allowed heap size has actually been allocated is not unusual for FOP while processing large input.
