This governor allows the user or a program in userspace to interactively change the processor frequency.
当处理器频率达到其极限时，一种流行的提高性能的方法是添加更多的处理器。
As processor frequencies reach their limits, a popular way to increase performance is simply to add more processors.
许多守护进程使用 userspace 调控器调整处理器频率；下面是几个例子
Numerous daemons work with the userspace governor to adjust the processor frequency; here are a few examples
他们并没有提升处理器频率，应该是为了保持硬件设计低成本和与一代相同的电力表现。
They didn’t improve the clock speed, presumably to keep manufacturing design costs low and to keep battery performance at parity with the first model.
从 2.6.0Linux内核开始，您可以通过CPUfreq子系统动态调整处理器频率。
Starting with the 2.6.0 Linux kernel, you can dynamically scale processor frequencies through the CPUfreq subsystem.
这些调控器根据特定标准设置处理器频率；其中一些根据系统或用户对输入的更改而动态更改频率。
These governors set the processor frequency based on certain criteria; some dynamically change the frequency as inputs are changed either by the system or the user.
最后，up _ threshold设置允许用户修改最大处理器利用率阈值，这个阈值触发处理器频率修改。
Lastly, the up_threshold setting allows the user to change the Max processor utilization threshold that triggers a change in processor frequencies.
此调控器还可以与在用户空间中运行的处理器频率守护程序结合使用来控制频率（我们将在第 2部分中讨论关于守护程序的更多信息，并提供一些示例）。
This governor also works with processor frequency daemons running in userspace to control frequency (we'll talk more about daemons and provide examples in Part 2).
微处理器内部逻辑操作的频率加倍，产生的热量也加倍。
Doubling the frequency of logical operations inside a microprocessor doubles the heat output.
性能调控器会静态将处理器设置为可用的最高频率。
The performance governor statically sets the processor to the highest frequency available.
显然，这有时会影响性能，因为无论处理器多么繁忙，系统都不会提高频率。
Obviously this can affect performance in that the system will never rise above this frequency no matter how busy the processors are.
此外，还有丰富的文档可供更改处理器设置时参考，从而最大程度地发挥基于当前电源动态调整频率的优点。
In addition, extensive documentation is available for changing your processor Settings to maximize the benefits of dynamic frequency scaling based on your current power source.
通常我们都认为是处理器的频率决定了性能的高低。
It's common to think that the processor frequency determines performance.
这表示一旦调控器发现处理器的利用率低于20%，它将逐步降低频率以节约电能。
This means that once the governor finds the processors to be less than 20 percent utilized, it will start stepping down the frequency to save power.
对双核内存测评结果不是很好，但是微处理器处理速度和时钟频率或是缓存空间相比要很好的多。
Benchmark tests are not perfect, but are a better indicator of microprocessor speed than clock rate or cache size specifications.
就像英特尔的超高时钟频率不能在提升了，双核内存也不能让微处理器的功能增大一倍。
Just like Intel's super high clock rates don't translate into proportionately more performance, doubling of cache size certainly doesn't double the performance of a microprocessor.
这意味着，内核将按照 sampling_rate 指定的时间间隔检查处理器利用率，如果低于百分之 20，调控器会降低频率。
This means that every sampling_rate, the kernel will check the processor utilization and if it is below 20 percent utilized, the governor will decrease the frequency.
cpuspeed：这个守护进程可以根据处理器需求、电源变化、温度等改变频率。
Cpuspeed: This daemon can change frequencies based on processor demand, power supply changes, temperature, and more.
首先，affected_cpus显示修改频率会影响哪些处理器。
First, affected_cpus shows which processors are affected by a frequency change.
powernowd：这个调控器守护进程根据处理器负载改变基本频率，用户可以选择四种行为模式。
Powernowd: This governor daemon bases frequency changes off of the processor load and has four different behavioral modes that users can chose.
接下来，cpuinfo_cur _ freq显示处理器当前的运行频率。
Next, cpuinfo_cur_freq shows the processor's current operating frequency.
在启用userspace调控器时，cpufreq - set实用程序让用户可以修改每个处理器的可用频率范围、使用的调控器和当前运行频率。
The cpufreq-set utility allows the user to change each processor's range of available frequencies, the operating governor, and the current running frequency when the userspace governor is enabled.
sampling_rate(以微秒为单位)决定调控器间隔多长时间检查处理器利用率，以便决定设置什么频率。
The sampling_rate, measured in microseconds, determines how often the governor will look at the processor utilization so that it can determine which frequency to set.
首先，up _ threshold默认设置为80，表示一旦处理器利用率超过80%，该调控器将提高频率。
First, the up_threshold is set to 80 by default, meaning that once the processor utilization reaches above 80 percent, the governor increases the frequency.
随需应变调控器：基于处理器的频率变更。
我花了2分40秒在运行频率为1654MHz的单cpu POWER 5处理器上安装了241个文件集。
It took me two minutes and 40 seconds, installing 241 filesets on a one-CPU POWER5 processor running at 1654 MHz.
现在一个电脑的处理器的频率通常是3.0GHz(每秒30亿次时针摆动)，这与三年或四前年制造的电脑没有太大的变化。
A modern PC typically has a processor running at 3.0ghz (3 billion clock ticks per second), little changed from a PC made three or four years ago.
想下这些数字（来自ARM），一颗1000毫安时容量的电池IntelAtomZ500处理器在频率800MHz运行时能支持19个小时的休眠时间，7小时的正常使用时间；
For a 1000 mAH battery, the Intel Atom Z500 Atom processor running at 800 MHz offers 19 hours of sleep time and overall battery life of 7 hours.
