  I have two servers, both running Powershell 5 on WIndows 2012 R2. Running the same Powershell script on one of the serveres takes a LOT more time than the other. On one server (using Measure-Command) it takes around 5-6 seconds, on the other server 30-50 seconds. Servers are virtual and of similar capacity, load seems to be similar.

  Details:

  Script.ps1:

  $text = "Hello World"
  $text

  Invoked by (at an elevated command prompt):

  powershell -file c:\temp\Script.ps1

  I have tried:

  Invoking the script with powershell -noprofile -executionpolicy bypass -file c:\temp\Script.ps1

  Restarting the WMI service

  Running the script for generating cached images:

  $Env:PATH = [Runtime.InteropServices.RuntimeEnvironment]::GetRuntimeDirectory()
  [AppDomain]::CurrentDomain.GetAssemblies() | % {
    $pt = $_.Location
    if (! $pt) {continue}
    if ($cn++) {''}
    $na = Split-Path -Leaf $pt
    Write-Host -ForegroundColor Yellow "NGENing $na"
    ngen install $pt
  }

  I have run Process Monitorand on the slow server, it loks like below (script was invoked on time stamp 10:22:52,0000), so something is blocking:

  

  And:

  

  Any ideas?
