Which performance tool is utilized to identify the specific step causing issues in a requestor session?

The Performance Profiler is specifically designed to identify the individual steps within a requestor session that are contributing to performance issues. By breaking down the execution of actions and revealing the time taken for each step, this tool helps developers and system architects pinpoint bottlenecks or slow operations within a process flow. This targeted analysis makes it easier to optimize specific segments of the process for improved performance.

Other tools serve different purposes; for example, the Performance Analyzer (PAL) provides a broader performance assessment by analyzing system performance metrics over time but does not pinpoint issues at the step level within a session. The Log File Viewer allows for investigation of logged events but is less focused on specific performance metrics. The Database Trace tool focuses on database interactions, which may not detail every step in a requestor session. Therefore, the Performance Profiler stands out as the most appropriate tool for diagnosing issues at a granular level within a requestor's activities.
