When exporting to PDF in report viewer it makes a call to server and regenerates report

When exporting to PDF in report viewer it makes a call to server and regenerates report. Is the report viewer not capable of exporting the already generated report? This is a significant issue for long-running reports (ie. 10 minutes). Exporting to PDF will take another 10 minutes (or more).

In order get the better performance with Report Viewer, apply below setting in Report Viewer to handle the larger amount data with less memory footprint. 

reportOption.ReportModel.EnableVirtualEvaluation = true; 
reportOption.ReportModel.DisablePageSplitting = true; 

Also, set the CanGrow true for necessary textbox report items alone because if  report having larger amount of data, then it will take time to measure height and width for larger amount of textboxes. Please refer the below documentation for your reference.

After the report rendered in Report Viewer, when click export it will not process it again. PDF export writes elements alone to the pdf document. Please apply the above code changes to reduce the export time.
