Start-BitsTransfer -Source $url -Destination $output -Asynchronous Start-BitsTransfer -Source $url -Destination $output BITS is primarily designed for asynchronous file downloads, but works perfectly fine synchronously too (assuming you have BITS enabled). If you haven't heard of BITS before, check this out. This method is also fully compatible on Server Core machines and 100% compatible with your Azure Automation runbooks. Anything that increases the performance of my scripts is a winner in my books. is my preferred option when file downloads are required. This isn't a major con, however sometimes it is handy to know how far through the transfer you are.

It essentially blocks the thread until the download completes or fails. There is no visible progress indicator (or any way to query the progress mid transfer). This can be very handy if you'd like your script to continue while the file downloads in parallel. Speed is great as the HTTP response stream is buffered to disk throughout the download process. Not as syntactically nice as Invoke-RestMethod - yet can still be executed on a single line. (New-Object ).DownloadFile($url, $output) NET class used for downloading files is the class.

If the script is to be run on a server running Windows Server Core, choose a more universal method.Ī common. Performance is good enough for small downloads, but there are definitely better options for situations where speed is required. This cmdlet shines when you need to persist cookies across multiple requests (for instance HTTP Forms Auth before downloading the file). In some cases you can use the -UseBasicParsing parameter, but it does not work in all cases. For example, this cmdlet cannot be used on Windows Server Core edition servers as the Internet Explorer binaries are not included by default. If anyone knows specifics on how this cmdlet operates, let me know!.Īnother potentially serious con for this method is the reliance on Internet Explorer. This adds a huge performance hit and potential memory issues for large files. Once the file has been fully loaded, it is flushed to disk. From what I have observed, the HTTP response stream is buffered into memory. Cookies can also be persisted between mutiple requests through the use of the -Session and -WebSession parameters. Integration with Write-Progress is handy while watching paint dry scripts run (assuming you know the total file size). With the cmdlet already available it is super easy to get started and use.

Write-Output 'Time taken: $((Get-Date).Subtract($start_time).Seconds) second(s)' Invoke-WebRequest -Uri $url -OutFile $output It is built into PowerShell and can be used in the following method: $url = '' The first and most obvious option is the Invoke-WebRequest cmdlet. I will be downloading a test file from Internode at the following URL: The scripts will be executed 10 times each with the average displayed as the result.

The test setup consists of PowerShell 4 running on Windows 8.1 圆4 with my VDSL connection curently synced at 35.9/10.4 mbps. The point is to show the difference in execution time and performance. Today's testing is not highly scientific. This post will describe three methods for downloading files using PowerShell - weighed up with their pros and cons. This blessing can equally be a curse as things can get complicated. NET framework enables almost unlimited possibilites inside the scripting realm. Perhaps the greatest strength of PowerShell is it's foundation on the.
