ISE slower than PowerShell.exe ?

Executing the same single command to create an application pool takes significantly longer to complete when ran in ISE or through Remote PowerShell when compared to just executing it in the powershell.exe command prompt.

I've seen it take up to 70 seconds to complete this simple command, at the same time when using the IIS GUI I can create an application pool while the other script is running in the background taking forever.

PowerShell.exe:

PS C:\> $t = measure-command { New-WebAppPool test8.com }
PS C:\> $t
