This is an interesting blog post, Green Computing with C++, about some real world projects which moved away from language X to re-implement their software in C++ and saw huge performance improvements.
Disclaimer: this isn't meant as flame bait, I know there is no one best language, but still sometimes it can be good to highlight concrete examples from industry. Also the author is clearly pro C++, so there is inevitably more emphasis it's strengths, for example in another post he goes to town on a C++ Hater (also a good read).

Have you heard of green computing? It’s basically the concept of lowering the energy requirements of computers in order to reduce the carbon footprint of datacenter operations and desktop/mobile applications
