Hi,
As Visakh16 pointed out, rendering directly from SQL Server report server should be faster.
Here are some tips for optimizing report processing:

If report performance is your top concern, use the following information to help optimize the time that is required to process your report:
•For reports that have many instances of text boxes, set CanGrow and CanShrink on text boxes to FALSE. By default, each cell in a Tablix data region contains a text box, so that total number
of text boxes that must be rendered can grow quickly.
•For reports that have many images, set AutoSize on images to a different value such as Fit.
•For text boxes, avoid setting the property TextAlign to General. This value requires conditional processing depending on the text box content.
•Avoid horizontal page breaks when they are not required. Review the margins, column widths, and white space in a report. For example, render the report to a .TIFF file and view it in the Microsoft
Windows Picture and Fax viewer to determine whether extra pages are being rendered.
Set the KeepTogether property on Tablix members only when you must control the specific rendering behavior for a Tablix data region. The KeepTogether feature requires extra processing when page breaks are calculated.
Hope the information helps.
