Performance when export/view report with PDF

[khoinh]

Hi,

   I am working with Cognos 8.4. I ran my report with HTML and its performance was well. However, when I checked it to view report with PDF, its performance is so bad (very slow). Could you give me your advices to tuning performance in PDF view?

Thanks

Hi,

Rendering a report as HTML will retrieve and display data for only the first page, and give you links to navigate to further pages (which again will be retrieved and rendered on-demand).  Rendering as any other format (including PDF) will retrieve the entire data set required for the whole report, and render all pages in one go.  Given this difference in behaviour, I'd expect the report to take longer to render as PDF than as HTML.  How many pages get returned?  Is there anything you can do to reduce the overall number of rows being retrieved?

Hi,

I saw you posted on the developerworks forum as well so I didn't add to that.  There is also a thread that may be of interest to you with regard to fine tuning PDF although as already mentioned a PDF report will take longer than HTML and the reduction or testing of the rows returned is the best first step.
