In this video you will learn how to use the Windows Performance Analyzer (WPA) tool that comes inside the Windows Performance Toolkit that allows use to look at the trace files generated by the Windows Performance Recorder (WPR). In this video you will see how to use the WPA to investigate and drill down to the root cause of high power consumption issues, in particulare you are shown the CPU idle states what the intended idle state was suppose to be (the target state) and what state was actually obtained (actual state).
- [Voiceover] Now, once your file is done loading…into Windows Performance Analyzer,…make sure you have an internet connection.…If you go to the top left corner,…you will see this Trace tab.…Click on it, and you will see this Configure Symbol Paths.…Select that, and by default,…you will see a line starting with srv.…The way to read this is that…the symbols are being grabbed from the Microsoft server…and being saved to your C: drive \symbols folder.…If that folder does not already exist, it will be created,…and that's where all of the symbols…that are downloaded from the server will be stored.…
So, click OK, and then go back to the Trace tab,…and this time, let's click on the load symbols.…And this is where you need your internet connection.…If you don't have the internet,…the symbols will load quickly,…because they have not really loaded at all.…While the symbols are loading,…let's expand this computation chart,…and underneath it, you are going to see…a CPU usage sample chart.…Let's click on this chart,…and drag it over to this big right-hand pane,…
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.
