Hey there To optimize query performance, consider the following steps below

Start by analyzing Query Execution Plans: Use tools like Query Store or SQL Server Management Studio to identify poorly performing queries and analyze their execution plans. Look for areas where indexes could be beneficial or where inefficient operations, such as table scans or nested loops, are occurring. Monitor Resource Utilization: Keep track of resource utilization metrics such as CPU, memory, and storage to identify any bottlenecks or resource contention issues. Azure Monitor provides insights into database performance metrics, allowing you to pinpoint areas of concern and scale resources accordingly.

Review Indexing Strategy: Ensure that your database tables are properly indexed to support common query patterns. Use tools like Azure SQL Database Advisor to analyze your database schema and recommend index optimizations based on query workload patterns.

If this helps kindly accept the answer thanks much.
