I have a relatively complex stored procedure that runs great. I can execute the sp via Management Studio New Query window and it takes less than 5 seconds to bring back the results.I created an SSRS report that simply does the same thing (in my feeble mind, anyway). I mean, this SSRS report does the same execute on the same sp. I deploy the report and go into the web browser and run the report and it takes up to 6 minutes! Way too long for any of my users to wait on this particular report.I feed it the same variables, etc. from both places SSMS and SSRS.I am doing these things from the same workstation, same user, same sever, etc.What are some things I need to be aware of, things I need to look for, to try and troubleshoot why kicking off the sp via SSRS takes so terribly much longer than running the same sp via SSMS query window?Thank you.Joel
