One of the more surprising aspects of GHC Haskell is that it is possible to write a very high level code with performance matching or exceeding code written in a low level language, thus honoring the machine. Stream fusion for an example. Not sure if there is any other language with higher abstraction/performance ratio.

JavaScript comes to mind. Its benchmarks are a wonderful testament to the immense engineering resources poured into V8.

  V8 is very impressive. But in exchange for its speed, it needs more memory. JS code optimized for speed tends to use more memory with Node.js than optimized Haskell or OCaml code: https://benchmarksgame-team.pages.debian.net/benchmarksgame/index.html https://benchmarksgame-team.pages.debian.net/benchmarksgame/...

Unfortunately, one space leak (extremely east to accidentally create in Haskell, much harder to debug than in other languages) cancels out all those benefits.
