PowerShell Job不会更快地运行

我将我的脚本转换为使用作业：

Start-Job "C:\Users\user\Scripts\PowerShell\SQL-Server\Database Anon\CreateSpoofDatabase_Resumes.ps1" { $args[0], $args[1], $args[2],  $args[3], $args[4] } -ArgumentList $ServerAddress, $DatabaseName, $ScriptPath, 1, $totalCandidate_create -Name "Resume_List1"
Start-Job "C:\Users\user\Scripts\PowerShell\SQL-Server\Database Anon\CreateSpoofDatabase_Resumes.ps1" { $args[0], $args[1], $args[2],  $args[3], $args[4] } -ArgumentList $ServerAddress, $DatabaseName, $ScriptPath, 2, $totalCandidate_create -Name "Resume_List2"
Start-Job "C:\Users\user\Scripts\PowerShell\SQL-Server\Database Anon\CreateSpoofDatabase_Resumes.ps1" { $args[0], $args[1], $args[2],  $args[3], $args[4] } -ArgumentList $ServerAddress, $DatabaseName, $ScriptPath, 3, $totalCandidate_create -Name "Resume_List3"
Start-Job "C:\Users\user\Scripts\PowerShell\SQL-Server\Database Anon\CreateSpoofDatabase_Resumes.ps1" { $args[0], $args[1], $args[2],  $args[3], $args[4] } -ArgumentList $ServerAddress, $DatabaseName, $ScriptPath, 4, $totalCandidate_create -Name "Resume_List4"
Start-Job "C:\Users\user\Scripts\PowerShell\SQL-Server\Database Anon\CreateSpoofDatabase_Resumes.ps1" { $args[0], $args[1], $args[2],  $args[3], $args[4] } -ArgumentList $ServerAddress, $DatabaseName, $ScriptPath, 5, $totalCandidate_create -Name "Resume_List5"

基本上，脚本将文本文件拆分为6个较小的文件，然后使用该文件列表调用简历创建脚本。简历创建只是使用模板并使用Word COM对象和来自SQL服务器的数据填充书签。

我只用一份工作来完成这项工作，我也用12来运行它，但它对创建简历的速度并没有什么影响。它总是大约每秒2。我可以看到它实际上是正确运行脚本的每个实例：

但我不确定为什么需要相同的时间。

检查工作的结果：

  

CandidateIDs1_part12.txt进度：39/90
  CandidateIDs1_part11.txt进度：52/101
  CandidateIDs1_part1.txt进度：45/101

调用脚本：

            WHERE personID = $candID" -ServerInstance $ServerAddress -Database $DatabaseName

        $firstName = $sqlResults.ItemArray[0]
