It turns out I don’t really use the UseProfile option, but I do use the Variable option. I bumped into some other things that made it so I had to add things to my scriptblock that were already in my environment.

One of them was snapins. I was trying to use some cmdlets from the Powershell Community Extensions and I had to add the snapin manually since it didn’t exist in the runspace by default.

The other was a function. I was changing a script to use Split-Job and it had a function declared in the script. Since there was no way of accessing that function inside the Split-Job scriptblock, I had to create the function in the scriptblock.

I think it would be great if it were possible to add more functionality like the $Variable parameter for the other environmental objects. One for Function, Snapin, and Environment in addition to the 2 you already have (Variable and Alias). This would almost totally eliminate the need for $UseProfile and still have it fast to load if you don’t need anything special.

I did one other change to give a better indication of progress. I changed the write-progess part to include a little more information. It gives me a better idea of the number of items in the Queue. That way you see if it’s slow because the scriptblock is slow or slow because it has 2000 objects to process.

Write-Progress ‘Split-Job’ `
“Queues: $($Pipelines.Count) QueueLength: $($QueueLength) Completed: $($QueueLength-$Queue.Count- $Pipelines.count) Pending: $($QueueLength- ($QueueLength-$Queue.Count))” `
-PercentComplete (100 – [Int]($Queue.Count)/$QueueLength*100)

Thanks for the work you’ve done on this. It makes Powershell much faster when you have a lot of systems to work on.
