Why Query Plan Cache is Important for SQL Server?
The query plan cache plays a crucial role in maintaining optimal SQL Server performance, contributing to several key benefits:
- Reduces Query Execution Time: By caching execution plans, SQL Server bypasses the need for repeated compilation and optimization, saving valuable processing time and expediting query execution.
- Improved Query Throughput: The minimized execution time for cached queries results into enhanced query throughput, enabling SQL Server to handle a higher volume of queries efficiently. As a result the queries are executed at a much faster rate.
- Overall System Performance: The efficiency gains resulting from the query plan cache extend to the overall performance of the SQL Server instance, contributing to a more responsive and scalable system.
- Saves compilation resources like CPU and memory.
