SSRS runs report for 30 sec however it takes only 3 sec in SQL Studio_问答_开发者

SSRS report calls sproc from SQL 2008 and it takes 30 sec to r开发者_运维技巧ender it.

If I call the same sproc with the same params it takes 3 sec to finish.

SQL server and SSRS are on the same box.

What can I do about it?

Sorry this isnt a comment, but thats not an option yet.

How many records are you returning? Have you looked in the report server execution table to see the times it is taking for data retreival vs rendering?

If the report has a large number of pages returned is the report streaming ie.. 1 of 2? or is it returning all the pages before rendering the first?

Does the report take that amount of time every time you call it or is it only the first time, basically once the plan is cached it is running quick? Could be complilation problems.

EDIT: Run this script against your report server DB. It will give you alot more information than you were looking for but, if you order by the report name you can view the data retrieval times, vs. processing time or process and render time. This will tell you where the time is actually being taken. Also your report server will be saving the last 60 days by default so if your only wanting say yesterday then uncomment the date between in the where clause.

Recently, I had experienced a very similar issue with a SQL query returning around 1000 rows of data relatively quickly (2 secs) on SSMS but the report itself took a few minutes to render the results.

Setting the report property "InteractiveSize" in SSRS forced the report to paginate the returned data instead of trying to render everything in one page.

This reduced the time taken to render the report down to 3 secs.

Are you on 2008 R2? If so, make sure you apply CU3, R2 was very buggy.

I've noticed a difference between using a data set that is set to call a stored procedure versus a data set that is set to use a text SQL query but all the text does is call the same SP.
