What must be done before capturing a profile with Guidewire Profiler?

Before capturing a profile with Guidewire Profiler, it is essential to clear the application cache. This step ensures that the profiler captures fresh and accurate data without any interference from previously cached information. When the application cache is maintained, it can hold outdated or irrelevant data that may lead to misleading results during profiling, making it difficult to analyze performance accurately or identify bottlenecks.

Clearing the cache provides a clean state of the application, allowing for a more precise measurement of resource usage and performance metrics. This is critical in the context of performance tuning, as it allows developers and administrators to base their findings on the current state of the application.

While backing up the database, refreshing the web browser, and disabling plugins may be necessary operations in different scenarios, they do not directly affect the accuracy of the profiling process as clearing the cache does. Backups are important for data security, refreshing the browser may create a smoother user experience, and disabling plugins may address compatibility issues; however, they are not prerequisites for accurate profiling.
