      PerfView is a performance analysis tool focusing on ETW information (ETL files) as well as CLR memory information (heap dumps). It can collect and view ETL in a variety of ways. Powerful grouping operators allow you to understand performance profiles in ways other tools can't. PerfView is used internally at Microsoft by a number of teams and is the primary performance investigation tool on the .NET Runtime team. Features include:
      • Non-invasive collection - suitable for use in live, production environments
      • Xcopy deployment - copy and run
      • Memory
        • Support for very large heaps (gigabytes)
        • Snapshot diffing
        • Dump files (.dmp)
      • CPU Performance
        • Support for managed, native, and mixed code
        • Can read XPerf logs
        • Profile diffing

      Updates in the 1.8.0 version include:

      • Various Win 10 ETW support
      • Support for opening VS2015 .DiagSession files
      • Suppport for new Self-describing ETW format.
      • Ability to look display the size of a IL DLL or EXE as a Heap in the viewer to understand why it is as big as it is
      • Support for resolving types and GC dumps for .NET Native executables.
      • Support for new symbol server format
      • Fixed issues displaying numbers HTML in non-english locals.
      • Support for showing the size of disk for a Directory in the stack viewer.
      • Added IIS checkbox to make collecting traces with detailed IIS information easy.
      • Overweight Analysis for determining why two traces differ quickly.
      • Support for EventSource V4.6 causality Tracking
      • Ability to capture every .NET Call being made (see .Net Calls in collection dialog)
      Updates in the 1.7.0 version include:

      • Added the 'Size' menu and the 'Directory Size' menu item for figuring out where disk space is going.
      • Enabled Goto Source for .NET Framework. Will fetch the source code from Microsoft's server so you can see inside .NET framework code.
      • Can turn on Network Capture to capture every network packet (See collection dialog box). Rudimentary parsing in the 'events' view
      • Net GC Allocations (as well as the original alot-ignore free) now possible for coarse sampling (the default)
      • Provider Browser in collection menu for exploring ETW events on the system (can look at manifset)
      • PerfView log from time of collection is storted in the etl.zip file and is available from the 'TraceLog' view.
      • 'Set As Default Grouping Menu Item' lets you set your default stack viewer parameters.
      • In the events' view you can select events and issue the 'Highlight in Histogram' to see where they are visually in the histogram.

      Updates in the 1.6.0 version include:

      • Bug fixes for some crashing issues when collecting heap dumps (IndexOutOfRangeException)
      • Better stacks in some cases where the stack transitions into the kernel
      • /WPR option that allows you to generate data as the WPR tool would (to view in WPA)
      Updates in the 1.5.0 version include:
      • Support so that ETL data of EventSource Events take with PerfVIew are viable with the WPA tool.
      • Can log performance counters to the ETL file using the /MonitorPerformanceCounter switch
      • Support for collecing working set data every half second (MemInfo)
      • PerfVIew is smaller and faster

      Updates in the 1.4.1.0 version include:
      • Added more /StopOn* options for stopping the circular buffer when paritcular events happen.
      • Support for events logged with WPP Software Tracing (place TMF files in an TMF directory)
