PSManageService

Proof of concept for reading services (Get-Service -ComputerName -Name ) with runspaces (parallel processing)

Project has 2 functions
  • Get-PSServiceNoRunspaces is just a wrapper around Get-Service. Merely makes sure that there is similar output/time measuring
  • Get-PSService - is runspaces in action.
Things to consider
  • The difference is 3minutes vs 42 seconds (for querying 10 servers for 2 services).
  • Where the 42 seconds is actually wait time for AD2 because AD2 is denying connectivity.
  • Since we ask AD2 x 3 times the 1st method takes over 3 minutes because it has to wait for termination before processing others.
  • Parallel version doesn't have to wait. It just waits in the end where all 3x AD2 terminate at similar time.
