使此脚本并行运行以加快执行速度的最佳方法是什么？

问题描述

此代码用于从嵌套组中获取所有用户。我希望它并行运行以加快运行时间。什么是最好的方法？我试图在我的最后一个函数的 foreach 上并行运行整个代码，但我无法在并行内部调用该函数。预先感谢已经遇到此逻辑的任何人。

    # $AduserCached = $resultHOlder
    $cachedResults = Get-Variable -Scope Global -Name $AduserCached  -ErrorAction SilentlyContinue
    if($null -ne $cachedResults){
     $existing = write-host "Check: i found existing"
     return $cachedResults.value,$existing
    }
    else{
     $searching = write-host "Check: Searching"
     $results = get-aduser $AduserCached -properties enabled,displayname,EmployeeNumber,LastlogonDate,PasswordLastSet
     Set-CachedADUSER -setAduserCached $AduserCached -value $results
     
     return $results.value,$searching
