Jasper Reports Performance

When a report returns large number of rows, the 'ignore pagination' property of the report should be set to false. If it is set true, the performance of the report is slow to render all the rows in a single page.

For cross tab reports, when the 'ignore pagination' is set false, the cross tab header will repeat every page when the report is export in to excel. To solve this issue, 'Repeat Column Headers' property of the cross tab should be set to false.
