Hello All,
How to increase BIRT performance as much as possible ? What the main keys of
its performance ?
In my case, I'm trying simple report based on two SQL queries. Count of
records in selected tables no more then 50. Time of the report generation
is unacceptable :
2 seconds on engine init ;
2 seconds on data source init ;
2-3 seconds on HTML rendering (first rendering - 5 seconds, next 1-2).
Are there any common advices ?
My environment - Eclipse 3.2M5a, birt-runtime-2.1RC4
Thanks in advance,
Andrey Dulub

I would like to use your approach to tackle BIRT performance. But, I am
not quite sure what do you mean by "Compile all *.rptdesign files into
*.rptdocument".
Do you mean to write a Java Application that uses the report engine API
to create .rptdocument files as shown below or there are other ways to
convert a rptdesign file to a rptdocument file?
//open the report design
IReportRunnable design = null;
design = engine.openReportDesign(REPORT_DESIGN);
//Create a task to run the report
IRunTask task = engine.createRunTask(design);
//Run the report and create the rptdocument
task.run(REPORT_DOCUMENT);
//Open the rptdocument
IReportDocument rptdoc = engine.openReportDocument(REPORT_DOCUMENT);
Many thanks,
Ling
