Memory Model is CONVENTIONAL

Altering the SQL Server memory model to LOCK_PAGES means that the OS cannot trim or page any memory being used by SQL Server until it's explicitly released.

LARGE_PAGES

If you're using SQL Server Enterprise Edition and have more than 8GB of physical RAM, then you could consider LARGE_PAGES as described in SQL Server and Large Pages Explained by Bob Ward (Microsoft).

Suggested Action

Consider enabling lock pages in memory.

How To Check SQL Server Memory Model
