Meh, they dismiss java &amp; pypy very quickly but they don&#x27;t understand that these languages require warm-up. If you benchmark runs in less than 2 seconds half of the time measured is starting the runtime, profiling &amp; compiling code. I think that interesting computational problems in economics have a much longer running time.<p>For this kind of algorithm, basically working with arrays of doubles, java should be within 20% of c++ and normally it is just as fast.
