Fibonacci Speed Test

[philiprbrenan]

Hi Raku:

On page: https://docs.raku.org/language/faq#Is_Raku_fast_enough_for_me? the recommendation is to test with:

perl -Mbigint test.raku

which does indeed produce an excessive time, perhaps 20 time slower than Raku. However, if one uses Perl correctly:

time perl -M'bigint=only,Pari' test.raku >/dev/null

real    0m0.770s
user    0m0.762s
sys     0m0.008s

as compared to:

time raku test.raku >/dev/null

real    0m0.605s
user    0m0.649s
sys     0m0.020s

for the specified test program cat test.raku:

my ($prev, $current) = (1, 0);

for (0..100_000) {
    ($prev, $current) = ($current, $prev + $current);
}
print $current;

one obtains a more balanced result.

May I therefore entreat you to update your documentation to reflect these important results?

Thanks

Thanks a lot for your suggestion. As you see, however, the point of the page is to show the speed of Raku, not the speed of Perl. In the new comparison it's still faster, although just a bit. Achieving a "more balanced result" is not the objective; since this is not a competition between Perl and Raku; the point is proving that Raku can obtain competitive results in this particular arena. In that sense, we could think about many different speed comparisons with many other languages (as Jonathan Worthington has done in his talks), in some of which, of course, Raku will be slower.
In a sense, you are right drawing our attention to this question, which might have outlived its usefulness, since nowadays the speed of Raku has improved to the point of being competitive with many other languages.

my 2¢ - we should do "fair" comparisons between the languages if we're trying to demonstrate speed.

However, given JJ's comment, rejecting this ticket.
