Box 1:

Box 2:

Box 3:

Note:
* SQL SERVER – 2008 – Optimize for Ad hoc Workloads – Advance Performance Optimization
Every batch (T-SQL, SP etc) when ran creates execution plan which is stored in system for re-use.
Due to this reason large number of query plans are stored in system. However, there are plenty of
plans which are only used once and have never re-used again. One time ran batch plans wastes
memory and resources.
* Let us now enable the option of optimizing ad hoc workload. This feature is available in all the
versions of SQL Server 2008.
sp_CONFIGURE ‘show advanced options’,1
RECONFIGURE
GO
sp_CONFIGURE ‘optimize for ad hoc workloads’,1
RECONFIGURE
GO

SQL Server 2008 has feature of optimizing ad hoc workloads.
