红帽全球峰会A.9. x86_energy_perf_policy
x86_energy_perf_policy 工具允许管理员定义性能和能源效率相对的重要性。它由 kernel-tools 软件包提供。
要查看当前的策略，请运行以下命令：
x86_energy_perf_policy -r
# x86_energy_perf_policy -r
要设置新策略，请运行以下命令：
x86_energy_perf_policy profile_name
# x86_energy_perf_policy profile_name
将 profile_name 替换为以下配置集之一：
- performance
- 处理器不会为了节省能源而牺牲性能。这是默认值。
- Normal
- 处理器可容忍细微的性能损失，从而可能显著节省能源。这是为大多数服务器和桌面节省合理的费用。
- powerave
- 处理器接受性能可能显著降低，以便最大程度提高能源效率。
