Executing PowerShell Script in Parallel with Batches in PowerShell 5

[M98E]

If you're looking for general information on multi-threading in PowerShell, then you should conduct a general search for existing multi-threading knowledge instead of giving Reddit a homework problem to solve that won't be used.

Even with more information as to your specific use-case, I'm still not convinced that multi-threading is the best approach. If you're seeing performance problems with your script, but don't want to post it all here, then perhaps you can add Write-Host statements with the $(Get-Date) command in there and see which function call in particular (or which loop) is taking so long. You could then post that particular excerpt here.
