Then how do you, Anonymous Monk, explain why JSON::XS is considerably faster than Storable in this example:
# 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__

No matter how great and destructive your problems may seem now, remember, you've probably only seen the tip of them. [1]
