​Platform Power Management

Platform-level power management can impact performance, particularly in low latency workloads. If performance is a higher priority than power consumption, it is recommended to experiment with modifying the CPU power management settings. There are many different ways to modify power management, through operating system tools, BIOS settings, and kernel boot parameters. Choose the best method and level to suit your environment.
