Time Windows applications launching (via Powershell?)

Question

I am supporting a piece of software in our organization that has an effect on the performance of applications, most notably the opening of applications (it's data loss prevention software that injects itself into processes to watch for data leaving the organization).

I was wanting to do benchmarks of applications opening in milliseconds with, and without the software in place, ideally some sort of automated process to launch the application, and time it starting up. Is there any way to do this precisely, such with Powershell?

Answer 1

You can use the Process Class (System.Diagnostics) in .NET to measure the execution time of a piece of code.

The following code sample uses this class to measure a PowerShell command.

Answer 2

You should try Measure-Command. Iit provides stas back that look like this:

Days              : 0
Hours             : 0
Minutes           : 0
Seconds           : 0
Milliseconds      : 81
Ticks             : 815066
TotalDays         : 9.43363425925926E-07
TotalHours        : 2.26407222222222E-05
TotalMinutes      : 0.00135844333333333
TotalSeconds      : 0.0815066
TotalMilliseconds : 81.5066

Syntax look like Measure-command {dir c:\ /s}
