A few hours ago, I wanted to show to my friends how speedy LuaJIT is. Naturally I went to the Computer Language Benchmarks Game website, but to my great surprise, LuaJIT is gone. I then posted a brief question in this blog asking why. Sindisil has very kindly pointed me to this informative discussion. In short, LuaJIT, along with a few other great language implementations, is gone and probably will never be back.
I have been watching this wonderful benchmark suite for several years and been greatly benefit from it. I really appreciate all that Issac, the owner of this website, has done. I know it must have been taking a lot of his own time.
This reddit discussion and a post from a core PyPy developer also point out the weakness of the benchmark, such as over-optimization for one implementation, the use of foreign libraries (especially C libraries), different coding qualities for different languages and the use of unusual/unportable optimization.
Perhaps it is time for someone to come up with a more proper, more open and less biased benchmark.
