Java v. C++, redux redux redux

Yet another Java/C++ comparison, this time for high-frequency trading, a sexy industrial programming area.

I found this quote most trenchant:

If you have a typical Java programmer and typical C++ programmer, each with a few years experience writing a typical Object Oriented Program, and you give them the same amount of time, the Java programmer is likely to have a working program earlier and will have more time to tweak the application. In this situation it is likely the Java application will be faster. IMHO.

In my experience, Java performs better at C++ at detecting code which doesn't need to be done. esp micro-benchmarks which don't do anything useful. ;) If you tune Java and C++ as far as they can go given any amount of expertise and time, the C++ program will be faster. However, given limited resources and in changing environment a dynamic language will out perform. i.e. in real world applications.

You decide.
