#2This is not an apples to apples comparison, the implemented Languages are fundamentally different. I do think this is an inspiring factoid that shows what is possible with a well done JIT.
Go Rubinius!

how are they very different? Syntax aside, Lua and Javascript are actually pretty similar. I would say they actually are close cousins.

Indeed, they are strikingly similar, one of the key differences being Lua's minimal/extensible dispatch. A function call, by default, involves no searching through superclasses/prototypes. This is likely a big advantage in benchmarks.

They really are quite different. Here's one example: http://lambda-the-ultimate.org/node/3851#comment-57751

JavaScript has multiple critical blunders in its specification that offer no advantage to the programmer, but are very difficult to optimize.

Which subclasses do you want to search through in JavaScript?
That said to me lua seems a little bit like JavaScript's sane cousin.

Define "quite different".

#10One question i have regarding these is how fair are the tests, a very quick look at the tests shows for "pidigits" the lua code has the line:
require"c-gmp"(g, aux)
Implying that it is using the GNU Multiprecision Library for it's big integer support, whereas the JS code has:
load('/home/dunham/shootout/bench/Include/javascript/biginteger.js');
Which is apparently a big integer library implemented in javascript http://www-cs-students.stanford.edu/~tjw/jsbn/
In other words, in at least one of the tests a comparison is being made between javascript and C/C++, not javascript and Lua.
