OSRunPriority Property
This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.
The OSRunPriority property controls execution thread scheduling for job steps executing operating system tasks.

Parts

Remarks
Set the OSRunPriority property to alter execution thread scheduling for job steps executing operating system commands. The property specifies a thread priority relative to that granted to an instance of Microsoft SQL Server.
Warning
Setting operating system thread priority can have adverse effects on other processes running on the server. Care should be taken when specifying priorities above normal.
