比較 managed & unmanaged code的執行效能

results shows that the optimization switches in managed C++ and C# have relatively small effects, and that there is only a 2% difference between managed and unmanaged code. Significantly, C# code is as good, or better than managed C++ or C++/CLI which means that your choice to use a managed version of C++ should be based on the language features rather than a perceived idea that C++ will produce 'more optimized code'.
