Report takes longer to print when suppressing rows

I have a report with a parameter that allows the user to choose if they want a detail view or a summary view. The summary view suppresses the details section. If this option is chosen, the report takes much longer to run. (10 minutes vs 80 minutes). Why does this occur? What can be done about it?

I am running CR 11 on a SQL 2005 database. The report returns about 800,000 records. There are around 100 formuals, most of which use global variables, and 3 grouping levels.

The detail version of the report comes in at about 270 pages, the summary version is 12 pages.

Let me know if you need any other details.

    Hi Ryan,

    Can you check what you have under performance information? Click Report (from the top menu) and select Performance information, select Performance Timing.

    Do you have Page of N function in your report? If yes, can you try without it?

    Can you test report with No Priner option?

    I understand there are no crosstabs or subreports in your report, am I correct?

    That helped tremendously. I removed the Page N of M from the report and checked the No Printer option. The report ran relatively quick finishing in about 5 minutes with only another 2 minutes to export to PDF. I decided to test with the "No Printer" option unchecked to see which solution had the impact in speed. The report ran just as fast with either the "No Printer" option checked or unchecked.

    To follow up on your other points. There are no subreports or crosstabs in this report. Here is the performance information.

    Before the changes.

    Open: 0 ms

    Run the Query: 95651 ms

    Read the Records: 124221 ms

    Format First Page: 325932 ms

    Number of Pages Formated: 2

    Avg. time to Format: 162966 ms

    Number of Page Starts: 12

    Average time to generate a page start: 245146

    After the changes.

    Open: 0 ms

    Run the Query: 97690 ms

    Read the Records: 85420 ms

    Format First Page: 213561 ms

    Number of Pages Formated: 1

    Thanks for the assistance.
