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__
$ perl -wl bm_storable_vs_json.pl Rate storable-arrayref json-xs-arrayref storable +-hashref json-xs-hashref storable-arrayref 6222/s -- -31% + -84% -99% json-xs-arrayref 8967/s 44% -- + -77% -98% storable-hashref 38280/s 515% 327% + -- -92% json-xs-hashref 501851/s 7965% 5497% + 1211% -- $

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