As explained video on the basics wall clock time investigations, the key to doing such an investigation is focusing in on a 'critical path' of interest.   For ASP.NET scenarios the most obvious such path is the time it takes to respond to any particular request.   PerfView supports this idea by creating the 'ASP.NET Thread Time view', by identifying the snippets of time on individual threads that represent work to respond to the request, and associating this cost to a particular request (and further grouping requests by URL.   This allows you to quickly segregate 'uninteresting' time where threads are simply waiting for work from the 'important' time when it is on the critical path to respond to a request.  The result that it is very straightforward to drill into performance problems on any particular request. 

There is a companion perfView blog entries that you may be interested in.   In particular there is a ZIP file of source code and data used in this tutorial, so that you can explore this data and 'follow along' yourself with what was done in this video.  To use the zip file simply open it, and drag the directory inside to your desktop (or other location).   The file contains an HelloWorld.ASPX file (the source code, just view in notepad) as well as the AspNetHelloWorld.ETL.ZIP file (The data file used in this video)   You don't need to unzip this file, simply open it in PerfView.

In the first video the demo was the simplest case, a sequential program with both disk and CPU time.  In this video we discuss the more complex case when there are several threads doing concurrent activity that you wish to analyze.  

The key PerfView feature that helps in cases like these is the 'Thread Time (with Tasks)', but only works if you use the System.Diagnostics.Threading.Tasks.Task class to spawn the concurrent activities.  In this view if one Task spawns another, the time associated with the subtask is attributed to the point at which the new Task was created.  Thus even though the work might be done on another thread, the cost is 'rolled up' based on the code that requested that that action be done.    This allows concurrent applications to be analyzed like the simple sequential case (where the cost of calling a routine is attributed to the routine that called it).

The first step in doing  .NET Memory investigation is first determine whether .NET Memory is your problem and take a heap snapshot.   This tutorial shows you how to determine how much of your process's memory is GC heap and (if that is your problem) shows you how to take a snapshot of the GC heap.    For large GC heaps, PerfView does not dump every object, but instead samples the heap (but goes to great lengths to insure that sample is representative).     This video describes this sampling and how to learn more about it. 

After watching this video you should follow up with the tutorial on investigating heap minemory leaks with PerfView.  You may also be interested in the whole PerfView Tutorial Series.

how easy it is to do this from C# by using a V4.5 Runtime class called System.Diagnostics.Tracing.EventSource (there is also a stand alone version for V3.5 or V4.0 runtimes).   The video goes through the process end-to-end from
creating the C# method to do the logging, through activating the logging using PerfView, and finally displaying the events in PerfView's 'events' view.

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 event that is logged in cronological order. This view is especially useful for finding 'when things happen' as well as see useful side information (like process command lines, and the version of all the DLLs in use).

The PerfView tool is a free Windows performance tool developed by the Microsoft .NET Runtime Performance team for investigating both managed can unmanaged performance problems. If you are having a performance problem, especially if it is a .NET application, it is hard to overestimate the value of this tool.

You can get the PerfView tool (for free) at the Microsoft Download center. (bing search on 'PerfView download'). PerfView consists of a single XCOPYable EXE so it is easy to simply 'try out'. You can literally open the .ZIP file, and double click on the .EXE inside to launch it and then follow along with the video tutorial. Ultimately you will want to copy this file out of the ZIP file (e.g. drag it to the desktop) to make it easier to launch.
