Visual Studio debugger PerfTips and the debugger-integrated Diagnostic Tools help you to monitor and analyze the performance of your app while you are debugging.

Although the debugger-integrated diagnostic tools are a great way of becoming aware of performance issues while you are developing, the debugger can have a significant impact on the performance of your app. To collect more accurate performance data, consider using the tools in the Performance Profiler as an additional part of your performance investigations. See Run profiling tools with or without the debugger.

PerfTips

When the debugger stops execution at a breakpoint or stepping operation, the elapsed time between the break and the previous breakpoint appears as a tip in the editor window. For more information, see PerfTips: Performance Information at-a-glance while Debugging with Visual Studio.
