更改 Chromebook 的性能设置

您的 Chromebook 可能会使用“超线程”功能来提升应用和游戏的性能

若要了解您的 Chromebook 是否具有该功能并详细了解安全风险,请访问我们的 Chromium 页面

重要提示:超线程会默认处于关闭状态以保护您,因为该功能可能会带来安全风险。所以,部分用户可能会发现设备在运行某些应用和游戏时速度变慢。

开启超线程 / 关闭超线程

chrome://flags#scheduler-configuration

  • 在“Scheduler Configuration”(调度程序配置)旁边,选择 Enables Hyper-Threading on relevant CPUs(在相关 CPU 上启用超线程)。

  • 在“Scheduler Configuration”(调度程序配置)旁边,选择 Disables Hyper-Threading on relevant CPUs(在相关 CPU 上停用超线程)。

  • 选择 Restart(重启)。

重要提示:若要切换回默认设置,请在“Scheduler Configuration”(调度程序配置)旁边依次选择 Default(默认)然后 重启(重启)。
