Hari Pulapaka and Boris Vidolov Performance Find Application Bottlenecks With Visual Studio Profiler he past decade has brought us many new software technologies and platforms. Each of these new technologies requires special knowledge to create greatperforming applications. As Internet technologies like blogs have now enabled frustrated users to easily cast a negative light on your applications, you really need to make performance a primary priority. Early in planning, you should add requirements for responsiveness and create prototypes to identify possible technology restrictions. Throughout development, you should also measure different performance aspects of the application to find possible regression, and ensure that testers file and track bugs for slow scenarios. Even with best planning, you may still have to investigate performance problems during product development. In this article, we will show you how you can use Visual Studio® Team System Development Edition or Visual Studio Team Suite to identify performance bottlenecks in your application. We’ll introduce you to the Visual Studio Profiler by walking through a sample performance investigation. Please note that while we used C# to write the code samples in this article, most of the examples here are equally valid for native C/C++ and Visual Basic® code as well. a small sample project that draws a Mandelbrot fractal as shown in Figure 1. This application is not very efficient and it takes approximately 10 seconds to draw the fractal. To start our investigation, we launch the Performance Wizard from the new Analyze menu in Visual Studio 2008. In Visual Studio 2005 this functionality is available from the Tools | Performance Tools menu. This launches a three-step wizard, where the first step lets us specify the target project or Web site. The second This article uses the following technologies: Visual Studio 2008 This article discusses: Targeting performance bottlenecks ✥ Application code profiling ✥ Comparison of profiling data ✥ Performance reports ✥ Code download available at: msdn.microsoft.com/msdnmag/code08.aspx Hari Pulapaka is a Software Design Engineer in Test who works on the Visual Studio Profiler team at Microsoft.

In his more than 10 years in the software industry, he has worked on many performance-critical applications. You can learn more about Boris at his personal blog, perfcop.spaces.live.com.
