Windows Performance Toolkit

Included in the Windows Assessment and Deployment Kit, the Windows Performance Toolkit consists of performance monitoring tools that produce in-depth performance profiles of Windows operating systems and applications. This documentation discusses both Windows Performance Recorder (WPR) and Windows Performance Analyzer (WPA).

Windows Performance Toolkit components

The Windows Performance Toolkit consists of two independent tools: Windows Performance Recorder (WPR) and Windows Performance Analyzer (WPA). In addition, support is maintained for the previous command-line tool, Xperf. However, Xperfview is no longer supported. All recordings must be opened and analyzed by using WPA.

The following are the system requirements for running Windows Performance Toolkit:

  • Windows Performance Recorder (WPR): Windows 8 or later.

  • Windows Performance Analyzer (WPA): Windows 8 or later with the Microsoft .NET Framework 4.5 or later.

Windows Performance Recorder

WPR is a powerful recording tool that creates Event Tracing for Windows (ETW) recordings. You can run WPR from the user interface (UI) or from the command line. WPR provides built-in profiles that you can use to select the events that are to be recorded. Alternatively, you can author custom profiles in XML. WPR can also be invoked and controlled by using the WPRControl application programming interface (API). For more information about the WPRControl API, see WPRControl API Reference.

For quick start of basic procedures, see the WPR How-to Topics. For complete documentation of the WPR UI, see WPR Features. For reference of command-line options, see WPR Command-Line Options. For discussion of key scenarios, see WPR Scenarios. For complete reference material, including a recording profile XML reference and a legacy Xperf reference, see WPR Technical Reference.

Windows Performance Analyzer

WPA is a powerful analysis tool that combines a very flexible UI with extensive graphing capabilities and data tables that can be pivoted and that have full text search capabilities. WPA provides an Issues window to explore the root cause of any identified.

For basic procedures and a detailed walkthrough, see the WPA Quick Start Guide. For complete documentation of the WPR UI, see WPA Features. For extended discussion of key scenarios, see WPA Scenarios.
