Windows 7 / Getting Started

Windows Performance Tools Kit

The Windows Performance Tools (WPT) Kit contains tools designed for analyzing a wide range of performance problems on Windows 7, Windows Vista, and Windows Server 2008. The types of performance problems that you can troubleshoot using the WPT Kit include application start times, boot issues, deferred procedure calls (DPCs), interrupt service routines (ISRs), system responsiveness issues, application resource usage, and interrupt storms. The WPT Kit is available as part of the Windows software development kit (SDK) for Windows Server 2008 or later and the Microsoft .NET Framework 3.5 or later. The WPT Kit is intended for use by system builders, hardware manufacturers, driver developers, and general application developers.

The WPT Kit is available as an MSI installer, one per architecture, and contains the Performance Analyzer tool suite, which consists of the following three tools:

  • Xperf.exe Captures traces and post-processes them for use on any machine and supports command-line (action-based) trace analysis
  • Xperfview.exe Displays trace content in the form of interactive graphs and summary tables
  • Xbootmgr.exe Automates on/off state transitions and captures traces during such transitions

Typical scenarios where you might use Xperf include:

  • Profiling applications or the system itself using sampling profiler mode.
  • Capturing Event Tracing for Windows data for later analysis.
  • Determining whether an application is I/O- or CPU-bound.

To use Xperf to capture a trace of a system, follow these steps:

  1. Install the WPT Kit on the system.
  2. Turn tracing on using the xperf -on provider command.
  3. Perform the activities you want to profile on the system.
  4. Capture a log file using the xperf -d logfilename command.
  5. Analyze your log file using the xperf logfilename command.
