PowerShell Studio - Performance Issue

Post by Trevis »

Hello,

I have a question about script performance in the PowerShell Studio 2015 (4.2.95). I wrote very short test script.

Running time in the Powershell Studio is longer then in the Powershell Console.

Can I ask someone for the explanation? Where is the problem? It has also impact to the (built) executable file.

This is the script:
PowerShell Code
Double-click the code block to select all.
$PerfStart = (Get-Date)
Get-Module -ListAvailable
$PerfEnd = (Get-Date)

Write-Host "Total time: " (($PerfEnd - $PerfStart).totalseconds)
Output from the Powershell Studio:
Total time: 20,9452221
Output from the Powershell console:
Total time:  3,9927442
Thank you.
Trevis

This is an automated post. A real person will respond soon.

Thank you for posting, Trevis.

Did you remember to include the following?
  • 1. Product, version and build (e.g. Product: PrimalScript 2014, Version & Build: 7.0.46. Version and build information can be found in the product's About box accessed by clicking the blue icon with the 'i' in the upper right hand corner of the ribbon.)
    2. Specify if you are running a 32 or 64 bit version
    3. Specify your operating system and if it is 32 or 64 bit.
    4. Attach a screenshot if your issue can be seen on the screen
    5. Attach a zip file if you have multiple files (crash reports, log entries, etc.) related to your issue.
If not, please take a moment to edit your original post or reply to this one.

The cmdlet is handled directly by PowerShell itself and not the host. Chances are that PowerShell console has already cached the values of the modules by the time you run the command.

If you add "Get-Module -ListAvailable" to the line before the timer you will see the difference it makes.
PowerShell Code
Double-click the code block to select all.
Get-Module -ListAvailable
$PerfStart = (Get-Date)
Get-Module -ListAvailable
$PerfEnd = (Get-Date)
 
Write-Host "Total time: " (($PerfEnd - $PerfStart).totalseconds)
