Process.PriorityBoostEnabled Property

Gets or sets a value indicating whether the associated process priority should temporarily be boosted by the operating system when the main window has the focus.

Namespace:  System.Diagnostics
Assembly:  System (in System.dll)

member PriorityBoostEnabled : bool with get, set

Property Value

Type: System.Boolean
true if dynamic boosting of the process priority should take place for a process when it is taken out of the wait state; otherwise, false. The default is false.

ExceptionCondition
Win32Exception

Priority boost information could not be retrieved from the associated process resource.

PlatformNotSupportedException

The platform is Windows 98 or Windows Millennium Edition (Windows Me), which does not support this property.

-or-

The process identifier or process handle is zero. (The process has not been started.)

NotSupportedException

You are attempting to access the PriorityBoostEnabled property for a process that is running on a remote computer. This property is available only for processes that are running on the local computer.

InvalidOperationException

The process Id is not available.

When a thread runs in a process for which the priority class has one of the dynamic priority enumeration values (Normal, High, or RealTime), the system temporarily boosts the thread's priority when it is taken out of a wait state. This action prevents other processes from interrupting the processing of the current thread. The PriorityBoostEnabled setting affects all the existing threads and any threads subsequently created by the process. To restore normal behavior, set the PriorityBoostEnabled property to false.

NoteNote

Boosting the priority too high can drain resources from essential operating system and network functions, causing problems with other operating system tasks.
