How to Measure How Long a Command Takes in PowerShell
Measuring how long a command takes to run helps when comparing approaches or identifying slow operations, and PowerShell has a built-in way to time execution. Windows 11’s PowerShell YYGACOR Login reports how long a command or block takes with a single wrapper.
The Command
Measure-Command { Get-ChildItem C:\ -Recurse }What It Does
`Measure-Command` runs the code in the braces and reports how long it took, showing the elapsed time in a detailed breakdown including total milliseconds and seconds. Here it times how long listing everything under the C drive takes. This is useful for gauging performance or comparing the speed of different ways to accomplish a task.
When You’d Use This
This is useful for comparing the speed of different approaches to a task, identifying slow operations in a script, or simply satisfying curiosity about how long something takes. When optimizing a script or choosing between two ways to accomplish something, measuring their execution times gives concrete evidence rather than guesswork about which is faster.
Useful Variations
You can place any command or multi-line block inside the braces to time it. To time a script’s overall run, wrap its invocation in `Measure-Command`. Note that `Measure-Command` suppresses the command’s normal output while timing it, so if you need to see results and timing together, other approaches capture both.
If It Doesn’t Work
Remember `Measure-Command` discards the visible output of the code it times, focusing only on duration, so if you need both results and timing, use a different approach that captures output separately. Times vary between runs due to caching and system load, so run several times and average for a reliable comparison, especially when the difference between two approaches is small.
Good to Know
`Measure-Command` discards the visible output of the code it times, focusing only on the duration, so use it when you care about speed rather than the results themselves. The elapsed time can vary between runs due to caching and system load, so averaging several runs gives a more reliable comparison when benchmarking.
Putting It Together
Once you have run it once or twice, this becomes second nature. As part of working with output and building simple automation, this command is a building block you will reuse constantly. As you combine it with the other scripting basics here, small one-off commands grow into reusable scripts that save real time on repetitive work. Like anything in the terminal, the real value comes from trying it on your own system and adapting the variations above to what you actually need, so it is worth experimenting with in a safe, low-stakes situation before relying on it in a script or during troubleshooting. Keeping a note of the commands you find most useful, along with the variations that fit your workflow, turns scattered one-off tricks into a personal reference you can draw on whenever a similar task comes up again.
