Powershell 3.0 - Workflows - Limit number of parallel execution

Question

I am cloning VMs on ESX server from template. Simplified code looks like this:

Workflow Create-VM {
  $List = 1..500
  foreach -parallel ($Elem in $List)
  {
            


        

Answer 1

There is an option to limit the number of parallel processes in a foreach-parallel loop using -throttlelimit N. It's great for reducing the parallelism, but if you try a high number the system may still limit you to 5, depending on all your software versions (YAY! Microsoft consistency). I know the question is old, but since it came up on Google without a decent answer, I thought I'd chime in.

Workflow Create-VM {
  $List = 1..500
  foreach -parallel -throttlelimit 4 ($Elem in $List)
  {
      # Create VM ...
      # Configure created VM ..
  }
}
