There are many ways to speed up a script.
- use the Get-VIew cmdlet instead of the regular PowerCLI cmdlets.
- use parallelism
- with Start-Job you can run a script multiple times in the background (fastest method for now afaik)
- use a PS Workflow
- use Runspaces, but note that due to the way PowerCLI currently works, you can't use multiple threads in the same Runspace
