In this video you will learn how to use the Windows Performance Recorder (WPR) tool that comes inside the Windows Performance Toolkit that performs event tracing. You will use the Windows Performance Recorder User Interface (WPRUI) to log power data related to a demo app. You will learn which event tracing options to select on the WPRUI and the impact each option can have on overall application performance.
- [Voiceover] I'll click start on the WPR UI,…and then I'm going to launch…the bouncing sprite application.…Once it is launched and goes into full screen mode,…I am not going to perform any user inputs.…I am simply going to watch the rubber band ball…bounce around the screen for 60 seconds.…After 60 seconds has passed on my stopwatch,…I'm going to come back to the WPR UI…and click save to stop the recording.…Also, earlier the FPS was being reported by Fraps.…
Here, I will not be running Fraps,…since that could skew the results.…Don't worry.…We will use Fraps later on to verify the FPS…after we optimize.…I will click start…and then launch the application under test.…Okay, so, 60 seconds is up,…so I'll go back to the WPR UI and click save.…When you click save, the recording will stop,…and a prompt will come up…for where you want to save the ETL file…and provide a comment about that recording.…
Here, for the comment I will put, "BouncingSprite High FPS,"…and I won't change where the ETL file is saved.…Click save, and when it's done saving, do not open the file.…
With these diagnostic tools and some efficient programming, you can reduce your app's power consumption while improving its response times. In this course, Thomas Pantels introduces a handful of tools used to measure and optimize power consumption. You will see demos on how to use the Intel Power Gadget, Windows Performance Toolkit, TypePerf, and SoC Watch, along with some simple coding tips for making any Windows app more energy efficient.
