Start by explaining which parts of SQL Server memory footprint are made up of. The memory consumed by SQL Server consists primarily of three parts: data caching (database buffer), execution caching (Procedure cache), and SQL Server engine programs. The caching of SQL Server engine programs is generally relatively small, and the primary focus of our memory tuning is on the control of data caching and execution caching. This article mainly describes the
