禁用CPUpipe理

如果我将下面的processor.max_cstate=0添加到启动的内核命令行，是否会禁用所有的CPU电源pipe理和调节？

我还发现： http : //www.experts-exchange.com/OS/Linux/Administration/A_3492-Avoiding-CPU-speed-scaling-in-modern-Linux-distributions-Running-CPU-at-full-speed- tips.html请

所有CPU /核心的链接都会将Change CPU调速器从“ondemand”改为“performance”，并从内核中禁用kondemand。

服务器用于虚拟主机

这将是您硬件设置的function。
请提供服务器make / model和Linux发行版/内核。

最大限度地提高服务器性能的过程，取决于您可以使用的内容，

例如：

Red Hat 6系统具有禁用CPU调速器的tuned-adm框架。（另请参见此图。）
HP ProLiant服务器（及其他）具有特定的调整指南和步骤，可实现低延迟和性能优化的设置。
大多数硬件供应商都有特定的BIOS设置可以帮助（禁用C状态和P状态 – 也是频率缩放）。

所以，请提供更多关于你在找什么的背景。

检查此答案中列出的matrix，以获取有关RHEL方法的一些常规信息。

编辑：从你的内核string，这似乎是一个红帽般的基于RPM的系统。

我会build议下载tuned-adm实用程序并更改系统的性能configuration文件来完成你想要的function。

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

要么会禁用CPU调速器。

系统设置和configuration文件按照以下日程安排：
