Hello,
there once was a similar question to this group but nobody gave a hint to a
solution, so I try it again. Does anybody use XML datasource without
performance problems, and if yes can provide an example report? I started
with BIRT 2.0.1, but the problem is still present in 2.1rc2.
I have a report basing on an XML datasource and three datasets defined for
the source, my report contains two subreports. I have no big amount of data
rows (2 in the main dataset with 1 and 1 resp. 6 and 7 in the datasets for
the subreport), but it takes 12 seconds to run and render the report. It
seems to me that the XML file is parsed multiple times, so the question is:
is there a cache to activate or do I have to use a special XML structure to
avoid the performance problem?
Thank you in advance, regards
Marc

Hello Jason,
thank you for your answer. Actually I already thougt that scripted data
source could be an alternative, but I was afraid that it might be too
complicated. But your result sounds promising, so I probably should give it
a try.
Do you think it's possible for you to send your report and data source as an
example to me?
Thank you again, regards,
Marc

Marc, can you please file a Bugzilla bug and attach the XML data and report
design that's giving you the performance problem? BIRT engineers can then
investigate.
thanks,

Hello Gary,
I created a new bugzilla bug (#140773) for the problem. I will try to
workaround using scripted data source, but I would rather use the XML file
as data source directly.
Regards,
Marc
