For the frequency downgrading policy, we observed the improvement on the energy usage criterion only for the workload resulting in 10\% system load. 584 As we were looking for the trade-off between total completion time and energy usage, we were searching for the workload load level that can benefit from the lower system performance in terms of energy-efficiency. For the frequency downgrading policy, we noticed the improvement on the energy usage criterion only for the workload resulting in 10\% system load. For this treshold we observed that slowdown in task execution does not affect the subsequent tasks in the system and thus total completion time of the whole workload. 585 586 585 587 586 588 Figure~\ref{fig:dfsComp} shows schedules obtained for Random and DFS strategy. One should easily note that the
