Aspose Cells for SSRS export taking a long time

We have a report that is rendered from a snapshot. Rendering from the snapshot takes seconds. Rendering from the db takes 3 minutes. Rendering to Excel 2007 via Aspose.Cells takes 14 minutes.

The report is 100K rows.

Is there a way to make this export faster? It’s pretty much useless the way it is. Users will not wait this long.

Hi,


Thanks for providing us some details.

Could you try to set Performance configurations, see the document for your reference:
http://www.aspose.com/docs/display/cellsreportingservices/Performance+Configuration

Thank you.

That page doesn’t really do a very good job of describing what the value of each parameter should be to extract the best performance.





In fact, after taking an even closer look, the documentation doesn’t even indicate what each parameter even does. How is this supposed to help?



Can you give some hints?

Hi,


We have fixed the method for TextBox's shrink and grow.


It makes export faster when you update performance settings in Aspose.Cells.ReporingServices.xml file.

Please try the fixed version: Aspose.Cells for Reporting Services (SSRS2008R2) V2.2.0.7 (attached).


Please copy Aspose.Cells.ReportingServices.dll into following folder : ${SQL Server 2008 R2 Reporting Services}\Reporting Services\ReportServer\bin.

Please let us know your run result.


Thank you.

This helped a small amount, but we still face extraordinarily long export times for files that are only 100MB or so.


When creating the export, does the Aspose code have to query the database again or does it use the cached snapshot? All of our larger reports are cached in report snapshots.

I wrote a quick program that selects 200,000 records from a table that has 440 columns and writes the output to a CSV file. Once the query ran, the time it took to create the CSV file was 1.5 minutes. The resultant file was 900 MB.

We also need to report another bug. When exporting to CSV, if a value in the data is blank, no “comma” is included for this value, so the column names will not align with the data.

About CSV rendering, we do not directly create CSV file.

We create excel file, then convert excel file to CSV file.
