Comentários

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.

Cuidado
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.
