Performance Tuning – Scenario Based

January 13th, 2011 No comments

Scenario 1
————
If an application makes multiple statement and each statement calls to a specific stored procedure. Thereby, being a multithreaded application it will call stored procedure multiple times at a time. It has been noticed that for some calls procedure takes longer time for different set of parameters. What could be the issue?

Solution 1
———–
First we can’t blame sqarely on stored procedure for the slower performance. We have few options here
1. Reduce the number of concurrent calls to stored procedure.
2. Check whether the procedure is calling any child procedure with input parameter or not. Suppose child procedure is looking for location and if parent procedure is passing location as an input parameter and while the absence of this input parameter child procedure might be processing all available locations, which could be in huge number, and consuming time. So before calling the child procedure, apply proper check which would reduce the time consumptions for remaining calls.
