Windows NT processor scheduling
|This article does not cite any references or sources. (January 2011)|
Windows NT processor scheduling refers to the process by which Windows NT determines which job (task) should be run on the computer processor at which time. Without scheduling, the processor would give attention to jobs based on when they arrived in the queue, which is usually not optimal. As part of the scheduling, the processor gives a priority level to different processes running on the machine. When two processes are requesting service at the same time, the processor performs the jobs for the one with the higher priority.
There are six named priority levels:
- Above Normal
- Below Normal
These levels have associated numbers with them. Applications start at a base priority level of eight. The system dynamically adjusts the priority level to give all applications access to the processor. Priority levels 0 - 15 are used by dynamic applications. Priority levels 16- 31 are reserved for real-time applications.
