H A Dsched-capacity.rst127 2. Task utilization
135 while task utilization is specific to CFS, it is convenient to describe it here
138 Task utilization is a percentage meant to represent the throughput requirements
143 On an SMP system with fixed frequencies, 100% utilization suggests the task is a
144 busy loop. Conversely, 10% utilization hints it is a small periodic task that
173 The task utilization signal can be made frequency invariant using the following
179 task utilization of 25%.
