Possible ways to increase report generation performance
Posted 02 April 2012 - 09:23 AM
Is there a way to speed up the generation of reports? We have creating PDF reports. I have searched Google and the forum and haven't really found any information regarding this. Just posts on how to get BIRT to use less memory. I have attached a graph which shows how the increase in records is impacting the increase in report generation time.
Let me know if there is anything else that I can provide to get better feedback such as the report design, etc.

In BIRT 3.7 you can deactivate the dataset cache (i think that this option was already existing in BIRT 2.6.x but didn't worked).
What's the Xmx setting on your dev machine? (you have to keep in mind that the postgres jdbc driver already loads the whole resultset into memory before even returning the first result row, because the set up looks like you are not streaming the rows)
