Once the CPU utilization of the application approaches 80% you will be hitting against the limits of the CPU, since cycles must be reserved for the base operating system itself.

一旦应用程序对CPU的利用率接近80%，您将遇到CPU的极限，因为必须为基本的操作系统本身保留周期。

The dynamic governors, which I discuss later in this article, can switch between CPU frequencies based on CPU utilization to allow for power savings while not sacrificing performance.

动态调控器(详见下文)可以根据CPU利用率来调整cpu频率，从而有助于节省电能，而不会牺牲性能。

Users were able to access their application, and the CPU incurred a decent load, going above 80% CPU utilization (10% kernel + 70% user).

用户能够访问他们的应用程序，CPU承受正常的负载，CPU利用率为80%多(10%内核+ 70%用户)。

By reusing TCP connections, TCP multiplexing can reduce CPU utilization by 60 to 90 percent depending on the application and the number of connections.

This not only improves application performance but also reduces server CPU utilization by as much as 30 percent, which potentially reduces the number of servers needed.

Notice in the screen shot that even though I have a dozen open apps and playing the HD file I am still only at 30% CPU utilization.
