Publisher description for Windows Performance Tools Kit
The Windows Performance Tools (WPT) Kit contains performance Analysis tools that are new to the Windows SDK for Windows Server 2008 and .NET Framework 3.5.The WPT Kit is useful to a broad audience,including system builders,hardware manufacturers,driver developers,and general application developers. These tools are designed for measuring and analyzing system and application performance on Windows Vista,Windows Server 2008,and later. The tools Currently include an xperf trace Capture tool,an xperfview visualization tool (also known as Performance Analyzer),and an xbootmgr boot trace capture tool. The tools are designed for the analysis of a wide range of performance problems including application start times,boot issues,deferred procedure calls and interrupt activity (DPCs and ISRs), system responsiveness issues,application resource usage, and interrupt storms.The MSIs containing these tools are available in the SDK bin directory. The tools are built on top of the Event Tracing for Windows infrastructure.ETW enables Windows and applications to efficiently generate events. Events can be enabled and disabled at any time without requiring system or process restarts. ETW collects requested kernel events and saves them to one or more files that are referred to as "trace files"or "traces." These kernel events provide extensive Details about the operation of the system.Some of the most important and useful kernel events that are available for capture and analysis are context switches, interrupts,DPCs process and thread creation and destruction,disk I/Os,hard faults,processor P-state transitions,registry operations,and many others. The tools use a trace capture and analysis model that follows this general flow: 1.ETW tracing is enabled by using xperf. 2.Operations are performed. 3.ETW tracing is disabled by using xperf, and the data is saved to an ETL trace file. 4.Trace files can then be further processed by using xperf or viewed by using Performance Analyzer.
