The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

SSRS "timerendering" is very slow

Asked by mortimer452 in SQL Reporting, MS SQL Server, SQL Server 2005

Tags: SQL Server, Reporting Services, SSRS

We have several reports setup in SSRS 2005 that are running very slow.

Through looking at the SSRS logs in the ReportServer database, we've deduced it is primarily the TimeRendering that is, by far, the slowest part of the report generation process.  TimeDataRetrieval and TimeProcessing combined may only be a second or two, whereas TimeRendering can sometimes be ten or twenty times that.

Here's an example:
TimeDataRetrieval: 3021
TimeProcessing: 3834
TimeRendering: 126339
ByteCount: 27331584
RowCount: 2178

Not an abnormally huge number of rows, I don't understand why the report is taking so long to render.  We've tried moving the report server to a different, much more powerful server with little affect on rendering time.

During the report generation, w3wp.exe on the SSRS server is pretty much pegged out the processor.

I haven't examined the .RDL files closely yet, I'm not super familiar with the report designer and "best practices" for designing reports.  Can anyone give me some insight on what might be causing the render portion to take so long?  Anything I should look out for or change in terms of design of the RDL's?

Thanks
