Re: [Factor-talk] benchmark comparing Factor to ANS-Forth

[John B. <mr...@gm...>]

Hi Hugh,

I'd love to see more benchmarks.  Feel free to contribute one!  Factor is a
lot faster than most dynamic languages because of native compilation,
although on some benchmarks JIT's like PyPy beat us.

Best,
John.
