大佬教程收集整理的这篇文章主要介绍了linux – 禁用CPU管理，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
该链接讨论了将cpu调控器从“ondemand”更改为所有cpu /内核的“性能”以及从内核禁用kondemand.

例如：
> Red Hat 6系统具有tuned-adm框架,可以禁用cpu调控器. (Also see this graphic.)
> HP ProLiant服务器(和其他)具有specific tuning guide和低延迟和性能优化设置的步骤.
>大多数硬件供应商都有特定的BIOS设置可以提供帮助(禁用C状态和P状态 – 也可以进行频率调整).
所以,请提供更多有关您正在寻找的内容的背景信息.
检查矩阵listed in this answer以获取有关RHel方法的一些一般信息.
编辑：从您的内核字符串,这似乎是一个类似Red Hat的RPM系统.
我建议下载tuned-adm实用程序并更改系统的性能配置文件以完成您想要的任务.
在你的情况下：
yum install tuned tuned-utils tuned-adm profile latency-perfoRMANce
或者可能：
tuned-adm profile enterprise storage
要么禁用cpu调控器.
系统设置和配置文件按照以下时间表排列：
