If you're running Visual Studio Enterprise, you can enable or disable IntelliTrace by going to Tools > Options > IntelliTrace. Select Settings in the Settings drop-down list to open the Diagnostic Tools Property Pages with more options. Use the Settings icon in the toolbar to select whether to view Memory Usage, UI Analysis, and CPU Usage. The Diagnostic Tools window shows information about events, process memory, and CPU usage. To open it manually, select Debug > Windows > Show Diagnostic Tools. When you start debugging in Visual Studio by selecting Debug > Start Debugging, or pressing F5, the Diagnostic Tools window appears by default. Performance numbers in the debug builds are less accurate, because debug builds lack these optimizations. Release builds provide optimizations like inlining function calls and constants, pruning unused code paths, and storing variables in ways that can't be used by the debugger.

For release build problems, decide whether features provided by the debugger-integrated tools will help to pinpoint the problem.

If the problem occurs only during debug builds, you probably don't need to run the non-debugger tools.

Check to see whether the issue exists in release builds.

For problems caused by CPU-intensive calls, there might be considerable performance differences between release and debug builds.

NET Object Allocation tool, are only available for non-debugger scenarios. Debugger-integrated tool results are most useful to compare with other debugging-related measurements, or to use debugger features.

Release build performance numbers in the Performance Profiler are the most precise and accurate.

The debugger itself changes performance times, as it does necessary debugger operations like intercepting exception and module load events.

External performance problems, like file I/O or network responsiveness issues, won't look much different in the debugger or non-debugger tools.

To decide which tools and results to use, consider the following options: Non-debugger tools give you results closer to the end-user experience. Debugger-integrated tools show you variable values and let you use breakpoints. The non-debugger Performance Profiler and the debugger-integrated Diagnostic Tools provide different information and experiences.

Windows 8 or later is required to run the debugger-integrated profiling tools. You can use the non-debugger performance tools with Windows 7 and later.
