Guidelines: Guideline from Red-Gates SQL Monitor tool: In general, Compilations/sec should be less than 10% of the Batch requests/sec. This is a global setting and is not specific to a datasource. High values often indicate excessive adhoc querying and should be as low as possible. As a result, the data file generated from the Person table will contain more fields than the Contacts2 table. As you can see, checking the DMV sys.dm_os_buffer_descriptors shows that most of the allocated pages on SQL Server 2017 are dirty, and on SQL Server 2008R2 the eager writer process took time to clean and write the pages on the tempdb data file.
