解説

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.

注意 :
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.
