Net Date/Time objects, but some other format. So the dates that are in the file system object are not. When the file system was original created many of the object types that we use every day didn’t exist. Too much data! This isn’t really a problem so much as a consequence of what the cmdlet is doing.Net file handling classes, which don’t support long files names–so nothing more than 260 characters in length. This might be your first question, and it’s a really good one! The core problem is Get-ChildItem isn’t the most performant cmdlet in your PowerShell toolkit, and let me outline a couple of problems with it. But are they faster? And if so, which one?

Nicolas1847, a PowerShell scripter on Spiceworks, has come up with an ingenious method to get simple directory information using Robocopy (of all things), and a colleague at athena health likes to shell out to CMD.exe and use the old DIR command. One piece I’ve never been able to speed up, though, is iterating through folders and files.

This has turned out to be a good habit now that I’m working at athena health, as the pure scale of things is so much larger than places I’ve been at in the past. By now, you may have noticed I’m always on the lookout for better performing code. The multithreaded program performed worse due to the overhead of creating 100 threads and forcing them all to wait with the mutex.

In fact, multithreading can be slower due to the overhead of creating the threads and context switching between them. If you program things where the tasks can’t be run in parallel and threads are waiting on each other frequently then the program will be slower. Is multi threading always faster?Ī multithreaded program will probably run faster if you program it right, assuming you have multiple cores. Instead of one file at a time using the copy feature built into File Explorer. One particular feature that makes Robocopy special (and often overlooked) is its multi-threaded feature that allows copying multiple files simultaneously. While copying will actually read and write the information to other place and hence takes more time. Generally, Moving files will be faster because when moving, it will just change the links, not the Actual Position on the physical device.
