This benchmark has been misleading for a while. It was originally made to demonstrate how JIT compilers can do all sorts of crazy stuff to your code - especially LuaJIT - and was meant to be a starting point of discussion about what exactly LuaJIT does and how.
As a result, its not indicative of what its performance may be on more realistic data. Differences can be expected because
- the text will not consist of hard-coded constants
- the number of words (and therefore the dictionary) would be larger, and JIT compilers for JS and Lua often have special optimizations for small dictionaries/tables
- the words wont be pre-split, and allocating new words adds significant performance penalty (in that case a trie would probably outperform other approaches)
Hello, I am not a coder and all the above is too complicated for me, after all your benchmark study would you have a clear comparison table that shows wich one from C++, V8, luajit or C is the most lightweight programing language and has the most very small memory footprint???
