Visual Studio应用程序运行极端慢调试
我有一个原生的c ++程序，当使用Debug（F5）启动时运行速度> 20倍，但在使用无调试启动（Ctrl + F5）时以正常速度运行。
I have a native c++ program which runs > 20 times slower when started with Debug (F5) but runs at normal speed when using start without debug (Ctrl+F5).
无论我使用debug还是release build都没关系。
It does not matter whether I use a debug or release build. Also if I use Windbg the program is a magnitude slower.
有没有一些设置我选择了错误或什么？
Is there some setting I did choose wrong or something?
将_NO_DEBUG_HEAP环境变量设置为1（如 http://preshing.com/20110717/the-windows-heap-is-slow-when-launched-from-the-debugger ）
Set the _NO_DEBUG_HEAP environment variable to 1 (as seen on http://preshing.com/20110717/the-windows-heap-is-slow-when-launched-from-the-debugger )
这也可以从Visual里面完成。
This can be done from inside Visual, too.
现在这只是一个解决方法，我很想知道如何重构遇到这种问题的程序。你有很多std :: map的，shared_ptr，或任何其他大的indirections任何机会？
Now this is just a workaround, I'm curious to know how to refactor a program which suffers from this kind of problem. Do you have many std::map's, shared_ptr, or any other big indirections by any chance ?
