Prioritized Task Scheduling API

优先任务调度 API

const promise = scheduler.postTask(myTask);

scheduler
  .postTask(() => 'Task executing')
  // Promise resolved: log task result when promise resolves
  .then((taskResult) => console.log(`${taskResult}`))
  // Promise rejected: log AbortError or errors thrown by task
  .catch((error) => console.error(`Error: ${error}`));

// IIFE
(async () => {
  try {
    const result = await scheduler.postTask(() => 'Task executing');
    console.log(result);
  } catch (error) {
    // Log AbortError or error thrown in task function
    console.error(`Error: ${error}`);
  }
})();

scheduler
  .postTask(() => 'Task executing', { priority: 'user-blocking' })
  .then((taskResult) => console.log(`${taskResult}`)) // Log the task result
  .catch((error) => console.error(`Error: ${error}`)); // Log any errors


// Check that feature is supported
if ('scheduler' in this) {
  mylog('Feature: Supported');
} else {
  mylog('Feature: NOT Supported');
}

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）。
