I'm playing around with Io and liking it. I'd like to understand its
performance characteristics. With a dumb integer arithmetic benchmark I
get Io as ten times slower than perl. Is this a more generally accurate
picture or not?
=== fib.io ===
fib := method(n,
if (n == 0, return 1)
if (n < 0, return -1)
a := 1; b := 1
n repeat (
c := a + b
a := b; b := c
)
return a
)
100000 repeat( fib(40) )
========
=== fib.pl ===
sub fib {
my $n = shift;
return 1 if $n == 0;
return -1 if $n < 0;
my ($a, $b) = (1, 1);
for (1..$n) {
my $c = $a + $b;
$a = $b; $b = $c;
}
return $a;
}
fib(40) for 1..100000;
========
$ time perl fib.pl && time io fib.io
real 0m0.904s
user 0m0.890s
sys 0m0.007s
real 0m9.454s
user 0m9.403s
sys 0m0.003s
