If a script runs slow, it’s not always obvious what causes the delays, and where to optimize. With a PowerShell module called “PSProfiler” you can test how long each line in a script takes to execute. It runs both in Windows PowerShell and PowerShell 7.
Start by installing the module:
PS> Install-Module -Name PSProfiler -Scope CurrentUser
Next, invoke your script with Measure-Script:
PS> Measure-Script -Path 'C:\Users\tobias\test123.ps1'
Once your script completes, you get a sophisticated report telling you exactly how often each line of your script was executed, and how long it took:
