在 Natty 中充分利用我的 Core 2 Duo 的速度

在 Natty 中充分利用我的 Core 2 Duo 的速度

我注意到我的电脑有时运行 Unity 很慢,但我无法使用 Gnome 面板的 Cpu Applet,因为 natty 面板有限制。有没有办法告诉系统使用整个 1.86 Ghz 的速度?两个核心独立工作。

答案1

默认情况下,您的 CPU 应该在“ondemand”调节器下运行,这意味着当它需要时它就会扩大规模。

如果您只是希望 CPU 始终以 1.86Ghz 运行,请cpufreq-selector -c 0 -g performance运行cpufreq-selector -c 1 -g performance

如果您使用cpufreq-info,您可以验证 governor 是否运行正常:

$ cpufreq-info

  available cpufreq governors: conservative, ondemand, userspace, powersave, performance
  current policy: frequency should be within 800 MHz and 2.10 GHz.
                  The governor "ondemand" may decide which speed to use
                  within this range.
  current CPU frequency is 2.10 GHz.
