Hi,
Creating PDF file using birt APIs is taking so much time. May i know the reason for it?
We are first generating a rptdoc file then from that i am rending the data and creating PDF file. This rendering data from rptdoc file and creating PDF file is taking so much time. Nearly 30 min it is taking. The output file size is 196 MB .
The PDF file has 1,25,000 pages
Can anybody provide the reason?
Thanks & Regards,
Laxmipathi Raju

Can you open a bugzilla entry for this and post the code below to it?
Also if you could post the design to it as well it would be good.
