Re: pidigits benchmark

Hi,
I think that is  because of it used  a dynamically compiled chunk.
The loadstring() function is not a fast funtion.

Hi,

Out of curiosity, does anyone have a technical explanation to offer
for why Lua performs up to 30x worse than Python and Perl in the
pidigits benchmark?

Hmm, also interesting, it appears to perform better on a gentoo
machine: http://shootout.alioth.debian.org/gp4/benchmark.php?test=all&lang=lua&lang2=python

I'd say the majority of performance in that benchmark completely depends on how GMP is compiled... definitely the type of benchmark that seems unfair to me... however it seems nearly all of the implementations of pidigits use gmp...
