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)。
