The Dynamic Power Savings Mode Response feature enables the System ROM to control processor performance and power state, depending on the processor workload. This option configures the response time for switching between these states.
The Fast setting is optimal for most workloads that require a low latency response to an increase in processor demand. The slow setting is optimal for some workloads where a longer latency response to increases in processing demand is an acceptable tradeoff for reduced power consumption. Depending on the processor workload, selecting this option may negatively impact performance.
