- It allows you to easily monitor, analyze, and troubleshoot query performance without manual analysis of system tables and logs
- The query profiler uses data from system views like SYS_QUERY_DETAIL to include performance metrics like execution time, input/output rows, and bytes read/written for each query step

- It provides a way to optimize queries by discovering performance bottlenecks
