PowerShell Tutorials : ForEach-Object -Parallel (Parallelism in PowerShell)

In this video I go over how to use the -Parallel parameter which is new to the ForEach-Object cmdlet in PowerShell 7, in the background it uses runspaces which have been around since V2. I will show you where -Parallel is good idea to use and also where it would be a bad idea and cause a longer script run time because of the resources and time needed to spin up these runspaces.

I go over how to use variables from outside the foreach loop as well as functions as using outisde functions and variables can be tricky in the foreach-object -parallel loops.
