Hi Guys, I'm hoping someone can point me in the right direction with this one. I have a ssrs 2005 report that runs with a stored procedure. In my development environment it runs in 1/5 minutes and in my Production environment it takes 5 minutes. Report and SP are all the same. Can someone point me in the right direction to check for the problem. Any help would be greatly appreciated.

Is there a big discrepancy in data volume between the two environments? Have you compared the execution plan on both systems? Are the indexes the same? Are statistics up to date in production?

As far as I can see, the stats are the same on both servers. I did notice after I ran a trace on prod, that it has a bunch of calls to a "EXEC DeadChunkPortion". The development environment doesn't have that. No difference in the data volumn. Execution plan looks the same. Any more suggestions would be very helpful as I struggle to find an answer

Could you post the execution plan from both systems?
