I am doing an evaluation of JasperReports and Birt reporting engines.
I designed a simple report in both tools where I give 20 values to the report as parameters and fill 6 other values from an SQL selection in the report as detail relation (this means that I have many rows of them).
I programmed the creation of both reports in Java and the PDF export (I think both reporting engines use iText)
I measured the time each report needed. The reports are exactly the same and they are ran from the same process.
The report was ran for 10 sets of values. So I measured the time for each of the 10 reports. The result was:
Printing Jasper reports for 10 values. Measuring time needed. 110 109 141 125 110 125 110 125 109 110 Jasper Finished!!!
Printing Birt reports for 10 values. Measuring time needed. 1063 1017 1095 1079 1063 1079 1048 1064 1079 1080 Birt Finished!!!
The numbers are in msecs.
Is it possible that Jasper is 10 times faster than Birt. Am I doing something wrong with my code that slows things down for Birt? I am posting the code I used in each case:
JasperReports:
// Export Jasper report
long startTime = System.currentTimeMillis();
JasperPrint myJasperPrint;
JRExporter myJRExporter = new net.sf.jasperreports.engine.export.JRPdfExporter();
try {
myJRExporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, "C:/Workspace/myProject/jasperReport" + reportNr + ".pdf");
myJasperPrint = JasperFillManager.fillReport("C:/Workspace/myProject/reports/testReport.jasper", jasperParametersMap, connection);
myJRExporter.setParameter(JRExporterParameter.JASPER_PRINT, myJasperPrint);
myJRExporter.exportReport();
return (System.currentTimeMillis() - startTime);
} catch (JRException ex) {
System.out.println(ex);
}
Birt:
// Export Birt report
String format = HTMLRenderOption.OUTPUT_FORMAT_PDF;
EngineConfig config = new EngineConfig();
config.setEngineHome("C:\\Tools\\Eclipse\\plugins\\org.eclipse.birt.report.viewer_4.2.2.v201302041142\\birt");
HTMLEmitterConfig hc = new HTMLEmitterConfig();
HTMLCompleteImageHandler imageHandler = new HTMLCompleteImageHandler();
hc.setImageHandler(imageHandler);
config.setEmitterConfiguration(HTMLRenderOption.OUTPUT_FORMAT_HTML, hc);
ReportEngine engine = new ReportEngine(config);
IReportRunnable report = null;
String reportFilepath = "C:/Workspace/EntireJ/Besuchblatt/reports/new_report.rptdesign";
HTMLRenderOption options = new HTMLRenderOption();
options.setOutputFormat(format);
options.setOutputFileName("C:/Workspace/myProject/birtReport" + reportNr + ".pdf");
long startTime = System.currentTimeMillis();
try {
report = engine.openReportDesign(reportFilepath);
}
catch (EngineException e) {
System.err.println("Report " + reportFilepath + " not found!\n");
engine.destroy( );
return;
}
IRunAndRenderTask task = engine.createRunAndRenderTask(report);
task.setRenderOption(options);
task.setParameterValues(parametersMap);
try {
task.run();
return (System.currentTimeMillis() - startTime);
}
catch ( EngineException e1 ) {
System.err.println( "Report " + reportFilepath + " run failed.\n");
System.err.println( e1.toString( ) );
}
engine.destroy( );
Is there a way to optimize Birt's performance in my case?
