可以使用System.Threading.Tasks.Parallel.ForEach方法来在PowerShell中实现并行循环操作。这个方法可以让循环中的迭代操作在多个线程中并行执行,从而提高处理速度。 powershellCopy Code # 示例代码$items=1..10[System.Threading.Tasks.Parallel]::ForEach($items, {Write-Output"Processing item:$_"Start-Sleep-Second...

This operator is functionally equivalent toStart-Job. By default, the background operator starts the jobs in the current working directory of the caller that started the parallel tasks. The following example demonstrates basic usage of the background job operator. ...
Beginning in PowerShell 7.0, theForEach-Objectcmdlet, which iterates items in a collection, now has built-in parallelism with the newParallelparameter. By default, parallel script blocks use the current working directory of the caller that started the parallel tasks. ...
Whichever approach you end up taking you will be getting PowerShell to run tasks in parallel. That will often require you to have additional instances of PowerShell running. The resources on your admin machine – CPU, memory and network bandwidth – are finite. Keep those in mind so you ...
and finally use that as input for the start-parallelexecution command, the core of this module, that in this case runs a single command, get-service to retrieve the list of services on each machine. All that runs as Powershell jobs through remoting sessions in parallel so can ha...
If you have script that can run independently and performs long running work that requires waiting for somethings to complete, then it makes sense to run these tasks in parallel. If you have 5 scripts that take 5 minutes each to run but spend most of the time waiting, you can have them...
Run tasks in parallel. Be interrupted—can be stopped and restarted, suspended, and resumed. Continue after an unexpected interruption, such as a network outage or computer/server restart.Workflow benefitsA workflow offers many benefits, including:Windows...
