Beta.9 - Invoke-WebRequest speed seems slow compare to Windows version but is not. #5284
Description
Compare execution of downloading a file using Invoke-WebRequest in both Windows PowerShell and PowerShell Core Beta.9. Beta.9 seems slower than Windows but is not. The progress bar in PowerShell Core is refreshing slower but in fact the process runs faster in Beta.9.
Steps to reproduce
Execute following command below in both Windows and PowerShell Beta.9:
Measure-Command {Invoke-WebRequest -Uri "https://github.com/PowerShell/PowerShell/releases/download/v6.0.0-beta.9/PowerShell-6.0.0-beta.9-win-x86.msi" -OutFile C:\Users\max_t\Downloads\PowerShell-6.0.0-beta.9-win-x86.msi}Expected behavior
Visually seems processing speed should be the same if executing the command on the same system.
Actual behavior
PowerShell Core Beta,9 progress bar refresh is a bit slower then Windows PowerShell.
But, the end results is that PowerShell Core Beta.9 runs a bit faster than Windows PowerShell.
