Tutorial 12 - Wall Clock Time Investigation BasicsThis is the first of a set of video tutorials on how to do wall clock time investigations with PerfView. It is best to watch the video using one of the high quality links on the right so the text is readable. Wall clock time is often the most interesting metric because it is the...

Tutorial 11 - Investigating .NET Heap Memory Leaks :Part2 Analyzing the dataThis video is the second in a two-part video on investigating a GC memory 'leak'. This video discusses a real world memory leak that was found and corrected in PerfView itself. If you have not watched part one, you should do so now. This second part assumes that we...

Tutorial 10 - Investigating .NET Heap Memory Leaks :Part1 Collecting the dataThis video is the first in a two-part video on investigating a GC memory 'leak'. This video discusses a real world memory leak that was found and corrected in PerfView itself. This first part discusses how you likely found the leak (by observing memory growth using TaskManager...

PerfView Tutorial 9 - .NET Memory Investigation: Basics of GC Heap SnapshotsThis video describes the basic information you need to start a NET memory investigation and in particular understand the data shown you in a .NET GC snapshot.
The first step in doing .NET Memory investigation is first determine whether .NET Memory is your problem and take a heap snapshot. ...

PerfView Tutorial 8 - Generating Your Own Events with EventSourcesIt may be that the ASP.NET events discussed in the previous video are diagnosting the performance of you service. However it not (or you are not using ASP.NET), you will want to log your own ETW events. This video shows you
how easy it is to do this from C# by using a V4.5 Runtime class... -
PerfView Tutorial 7 - Using the Event Viewer in ASP.NET ScenariosIn the previous video learned the basics of using the event viewer. In this video we use that knowledge in a common scenario: investigating the performance of an ASP.NET server scenario. The video discusses the ASP.NET ETW events as well important fields like the 'ContextID' field that let you quickly...

Perfview Tutorial 6 - The Event Viewer BasicsIn the first tutorial we used the 'Run' command to caputure data while an executable ran. In tutorial 2-5 we learned how to use the StackViewer to do a CPU investigation. In this tutorial we learn more about a very different view called the EventViewer that allows you to look at ALL the data in each...

PerfView Tutorial 1.1 Data Collection for Server ScenariosIn the first tutorial we used the 'Run' command to caputure data while an executable ran. However for server scenarios you simply want to explicitly state when to start and stop data collection. It is also likely that you will need to ask someone else...

PerfView Tutorial 1 - Collecting data with the Run command
Jul 22, 2012 at 6:58 AMThere are high quality video links just to the right of the right that you can click on (I mention that in the text below the video frame). I recommend the WMV version (it is the original).
To answer MagicAndre1981's question, I am a big fan of XPerf/WPA, and work with that team to make it better. If you are happy with WPA, certainly stick with it, it is a very powerful tool. I like to believe that most of the knowledge you learn in using one tool is applicable to the other.
As to why we have both, the simple answer is that XPerf had a codebase (originally completely unmanaged), and and a installed-base / client base (the OS guys), that make it evolve in a certain direction and at a certain rate. Historically it did not suppport managed code well, and adding extensions is harder than you would like. Originally the goal was simply to have a managed code interface to ETW data. However once you have this, you start wanting to explore better/different ways of presenting the data, which is the genesis of PerfView.
For what it is worth...
PerfView Tutorial 1 - Collecting data with the Run command
Jul 17, 2012 at 10:11 AMYes, I actually just now noticed that. In fact the C9 team did get a hold of me back in January. The delay is all my doing. The last several months has been a big push for us to get Win8 ready, and only now are things calming down. Anyway better late than never...
