Profiling and diagnostics tools help you diagnose memory and CPU usage and other application-level issues. In software engineering, a profiler is a tool used to help you analyze the performance of your applications to improve poorly performing code. There are several ways to diagnose performance issues when you’re working with APIs, but using a profiler can help you quickly identify and rule out possible causes so that you have a clear path in resolving your issue.
