I should note that power and performance are not opposites. Good power management ensures you don't waste power, which helps you draw all you need when you need it by the component that needs it. Good power management often helps overall performance.
One thing that it often works against is latency, because it takes time to wake up things that are sleeping. But that is really not something you should care about if you're using a laptop. Your laptop is not servicing Google search results.
- papermachete 7y agoPerformance is a solved problem nowadays, latency isn't. Especially with cloud-based software being pushed. The benefits of a tweaked linux kernel, such as liquorix are easy to spot. Yes, slightly reduced brute performance but large leaps in smoothness.
- drewg123 7y agoYes, it often does in a broad sense. But there is a lot more to power management. Things like putting busses and devices into low power states when idle, and batching up I/O so that devices can spend most of their time in low-power states. Scheduler tweaks to idle most of the cores, etc.
