Instant File Initialization In DMVs

Rodney Landrum shows off a couple new columns in SQL Server 2016 SP1 DMVs:

Microsoft announced many new features in SQL Server 2016 SP1 and the fanfare was mostly centered around the Enterprise features now available in SQL Server 2016 Standard Edition.  Many may have missed some hidden gems in the announcement.  Two of these are columns added to the existing DMVs, sys.dm_server_services and sys.dm_os_sys_info. The columns provide information for two specific features that previously had to be gathered by opening gpedit.msc and/or scrolling through SQL error logs. I am referring to Lock Pages in Memory and Instant File Initialization (enabled via Perform Volume Maintenance Tasks privilege).

It is now possible to simply query the DMVs to determine if these are being used for the running SQL Server instance.

One of the top written to tables was, based on our naming convention, a […]
