Question

是否有Windows等效的Unix命令， nice ？

我特意在命令行中查找可以使用的内容，并且不来自任务管理器的“设置优先级”菜单。

我在Google上发现这种情况的尝试已被那些无法提出更好形容词的人所挫败。

Answer 1

如果要在启动进程时设置优先级，可以使用内置的启动命令：

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

使用low through belownormal选项设置已启动命令/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过程。

Answer 2

如果使用PowerShell，您可以编写一个脚本，让您更改进程的优先级。我在Monad blog上找到了以下PowerShell函数：

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，您可以执行以下操作：

set-ProcessPriority SomeProcessName "High"

Answer 3

也许您要考虑使用ProcessTamer根据您的设置“自动化”降级或升级流程优先级的过程。

我已经使用它两年了。它非常简单但非常有效！

use Win32::OLE;
$Win32::OLE::Warn = 3;

use constant NORMAL => 32;
use constant IDLE => 64;
use constant HIGH_PRIORITY => 128;
use constant REALTIME => 256;
use constant BELOW_NORMAL => 16384;
use constant ABOVE_NORMAL => 32768;

# ------ SCRIPT CONFIGURATION ------
$strComputer = '.';
$intPID = 2880; # set this to the PID of the target process
$intPriority = ABOVE_NORMAL; # Set this to one of the constants above
# ------ END CONFIGURATION ---------

print "Process PID: $intPID\n";

$objWMIProcess = Win32::OLE->GetObject('winmgmts:\\\\' . $strComputer . '\\root\\cimv2:Win32_Process.Handle=\'' . $intPID . '\'');

print 'Process name: ' . $objWMIProcess->Name, "\n";

$intRC = $objWMIProcess->SetPriority($intPriority);

if ($intRC == 0) {
    print "Successfully set priority.\n";
}
else {
    print 'Could not set priority. Error code: ' . $intRC, "\n";
}

PrcView似乎也在命令行中运行：
