Then how do you, Anonymous Monk, explain why [mod://JSON::XS] is considerably faster than [mod://Storable] in this example:
<c>
# Benchmark
use warnings;
use strict;
use Benchmark qw(cmpthese);
use Storable qw(freeze thaw);
use JSON::XS;
my $hashref = { one => 1, two => 2, three => 3, four => 4, five => 5 };
my @array = (1 .. 1000);
cmpthese(
-1,
{
'storable-hashref' => sub {
my $foo = thaw(freeze($hashref));
},
'storable-arrayref' => sub {
my $bar = thaw(freeze(\@array));
},
'json-xs-hashref' => sub {
my $foo = decode_json(encode_json($hashref));
},
'json-xs-arrayref' => sub {
my $bar = decode_json(encode_json(\@array));
},
}
);
__END__
</c>
