Windows等效的“ nice”

Windows是否有与Unix命令等效的Windows，nice？

我专门在寻找可以在命令行中使用的内容，而不是任务管理器中的“设置优先级”菜单。

那些无法提出更好的形容词的人挫败了我在Google上发现此内容的尝试。

如果要在启动进程时设置优先级，可以使用内置的START命令：

START ["title"] [/Dpath] [/I] [/MIN] [/MAX] [/SEPARATE | /SHARED]
      [/LOW | /NORMAL | /HIGH | /REALTIME | /ABOVENORMAL | /BELOWNORMAL]
      [/WAIT] [/B] [command/program] [parameters]

使用低至低于正常的选项来设置启动的命令/程序的优先级。似乎是最直接的解决方案。没有下载或脚本编写。其他解决方案可能适用于已经运行的proc。

如果使用PowerShell，则可以编写脚本来更改进程的优先级。我在Monad博客：

function set-ProcessPriority { 
    param($processName = $(throw "Enter process name"), $priority = "Normal")

    get-process -processname $processname | foreach { $_.PriorityClass = $priority }
    write-host "`"$($processName)`"'s priority is set to `"$($priority)`""
}

在PowerShell提示符下，您需要执行以下操作：

set-ProcessPriority SomeProcessName "High"

也许您想考虑使用ProcessTamer来根据您的设置“自动”执行降级或升级过程优先级的过程。

我已经使用了两年了。这很简单，但确实有效！
