    How to increase Performance of SQL Procedure?

    I would think that the stored procedure is creating loads of temporary tables or something. Also to note: THE MAJORITY OF PERFORMANCE ISSUES ARE THE CODE THAT ACCESSES THE DATABASE, NOT THE CONFIGURATION ITSELF. Post you stored procedure if possible. Cal
