![]() This counter shows the percentage of time the processor spends on the execution of Microsoft Windows kernel commands, such as processing of SQL Server I/O requests. ![]() Also, there is no idle value for this counter. So we retrieve CPU intensive queries to get the culprit transactions that are causing high CPU pressure. If this counter is high then it means CPU pressure is because of SQL Server or because of user applications. This counter shows the percentage of time a process spends executing user processes like SQL Server. But if tt frequently reaching beyond 85% then it means the system is facing a CPU bottleneck. The value of this counter must be less than 50%. This counter displays the percentage of time the CPU spends executing a thread that is not idle. Here is the list of performance counters that we look at to identify SQL Server CPU bottlenecks. If the CPU utilization is continuously going beyond 85% then it means the system is facing a CPU bottleneck. We first look at CPU usage in Windows Task Manager. ![]()
