Abstract
A technique for expediting an operation in a computer system involves raising the priority level of an operating system task from a low priority level to a high priority level in order to perform the operation at the high priority level and lowering the priority level of the operating system task back to the low priority level upon completion of the operation. Task priority control logic causes the operating system task to execute at the low priority level as a default priority level. The task priority control logic monitors for a trigger condition indicating that the operation is to be performed. Upon detecting the trigger condition, the task priority control logic raises the operating system task to the high priority level, and begins monitoring for completion of the operation. Upon determining that the operation is complete, the task priority control logic lower the operating system task back to the low priority level.
