This is a very heavy test of non optimizable recursion, and (benchmark not published yet) ArkScript is only 2 times slower than JavaScript. It sounds a lot, but please note that I'm actively working on improving those numbers, and I'll add other benchmarks (fast allocations of lists and more) to have a better idea of what the language is capable of in term of speed.

That statement does not help. Which implementation of Javascript and what kind of benchmark is only 2x faster?

For starters, here is a good overview of Javascript interpreter performance:

Woops sorry

I used the Ackermann Péter fucntion, still the same parameters (3, 6), on spidermoney (js engine for Firefox 74.0, windows 10, i7 8k)

Thanks for the link, I'll definitely dig down into that!
