Extend your battery life with scx_rustland
Overview The CPU scheduler can play a significant role to save energy in the system. Typically we talk about Energy Aware Scheduling (EAS)...
Modern CPUs’ power consumption is heavily influenced by how long they remain idle, sometimes yielding more significant energy savings than Dynamic Voltage and Frequency Scaling (DVFS) techniques (e.g., the cpufreq governor). Real-world tests showed around 20-30% increase in laptop battery life using scx_rustland in low-power mode with typical workloads like reading emails, web browsing, listening to music, and compiling code. Avoiding idle states for CPUs in the same core as an active CPU, for example, could minimize unnecessary throttling of CPU-intensive tasks while maintaining, potentially, the same level of energy savings.
