ABSTRACT:
A method for dynamically scaling consumption of processor cycles by a task executing in a multi-tasking input/output subsystem, wherein a performance task executing in the multi-tasking input/output subsystem determines a real-time error measure that indicates a number of real-time errors logged by at least one input/output driver executing in the multi-tasking input/output subsystem. If the measure of real-time data gathering errors exceeds a predetermined threshold, then the consumption of processor cycles consumed by the task is reduced.
