The Application Tuning Case Study
In this section we compare and contrast the three code profilers that we used to examine the application’s consumption of processor cycles. All the tests were made on a Windows NT 4.0 Server installation, but the results apply to the Windows 2000 environment with almost no modification. Overall, we found both compiler add-on packages to be extremely useful and well worth the modest investment. Visual Quantify provides a highly intuitive user interface. It extends the CPU profiling information available through the built-in facilities of MS Visual C++ by incorporating information on many system services, and it greatly increased our understanding of the code’s interaction with various Windows 2000 system services. VTune supplemented this understanding with even more detailed information about our code’s interaction with the Windows 2000 runtime environment. VTune’s unique analysis of Intel hardware performance provides singular insight into this critical area of application performance.
Visual C++ Profiler
The first stage of the analysis used the code execution profiler built into MS Visual C++. This is a natural place for any tuning project to begin given that no additional software packages need to be licensed and installed. Runtime profiling is enabled from the Link tab of the Project, Settings dialog box inside Developer Studio, which also turns off incremental linking. Profiling can be performed at either the function or line level. Function-level ...
