database record in the main report.) As an alternative, consider using

linked on-demand subreports in the Details section of your main report.

Linking tables instead of linking subreports

Whenever possible, coordinate your report data by linking database tables

on the Links tab of the Database Expert, rather than by linking regular

subreports—that is, subreports that aren't on-demand subreports—to the

main report. Since each subreport is run as a separate report, linked tables

often have a performance advantage.

Maps

Map rendering is a single-threaded operation that does not scale well.

Although maps are supported, you need to be careful in considering the

overall effect a map in your report will have on performance.

Report Templates

If you will be applying the same template to multiple reports, it is best to open

the report once and cache it, because the template only needs to be

read-only.

Including "Page N of M" or "Total Page Count"

If you include the special fields "Page N of M" or "Total Page Count" in your

report, the report needs to finish processing before it can calculate this value.
