Lisp (Common Lisp) beats all the other dynamic languages by a considerable margin. This is why I am developing Clasp - a Common Lisp implementation based on LLVM that interoperates with C++/C (https://github.com/clasp-developers/clasp.git) for scientific programming. With Clasp, we get the best of multiple worlds. We get a dynamic language (Common Lisp) with automatic memory management and enormous expressive power that can directly use powerful C and C++ libraries. All three of these languages are "long-lived"…

I see similar postings coming by on LinkedIn now and then. Although there is some value in the benchmark results, the way these results are promoted is such a BS. If your company's business is really in running some algorithms similar to binary search or the n-body problem, you should probably not be checking which language to choose that is most energy efficient, but which library or framework suits you the best. E.g you can perfectly well use Python +…
