We are after those sql jobs that continuoslyCPU spike. my question is how do I prove that db stored procedures etc are not slow...and that the slowness is due to 1. Now that we know SQL Server is the main culprit and responsible for the high CPU, the next step is to find out which SQL Server process is causing the high Unless you know exactly where your query performance issues lie, however, you should always start with a system performance evaluation. navigate here
