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.

[ What is claimed is:] [1.] A method for dynamically scaling consumption of processor cycles by a task executing in a multi-tasking input/output subsystem including a plurality of tasks each associated with an input/output driver, comprising the steps of:executing an error logging function that increments a global error count variable each time a real-time error is reported by a first input/output driver of the subsystem;determining a real-time error measure indicating a number of real-time errors reported by the first input/output driver by averaging a number of real-time errors reported by the first input/output driver over a predetermined time interval; andreducing the consumption of processor cycles used by the task if the real-time error measure exceeds a predetermined threshold, wherein the task is associated with a second input/output driver.
