Instrumentation and Performance Windows 7 includes new Event Tracing for Windows (ETW) capabilities that developers can take advantage of during the development process to optimize application performance. Instrumentation has always been part of Windows, but Windows 7 includes new ETW underlying technology that makes the task of including instrumentation in your application a whole lot easier. <br />This unit describes the different options for using instrumentation in Windows, including the new ETW. Hands-On Labs Instrumentation and Performance In this lab you will instrument an application, using Windows performance counters, so that it can be inspected programmatically and remotely. Additionally, you will analyze the performance of an application externally, without modifying its source code, by using the Windows Performance Toolkit.
