NAME Benchmark::Serialize - Benchmarks of serialization modules

SYNOPSIS use Benchmark::Serialise qw(cmpthese);

    my $structure = {
        array  => [ 'a' .. 'j' ],
        hash   => { 'a' .. 'z' ]
        string => 'x' x 200,
    };

    cmpthese( -5, $structure, qw(:core :json :yaml) );

DESCRIPTION This module encapsulates some basic benchmarks to help you choose a module for serializing data. Note that using this module is only a part of chosing a serialization format. Other factors than the benchmarked might be of relevance!

Included is support for 24 different serialization modules. Also supported
is the Data::Serializer wrapper providing a unified interface for
serialization and some extra features. Benchmarking of specialized modules
made with Protocol Buffers for Perl/XS (protobuf-perlxs) is also available.

See the in-module documentation for more information.

RESULTS

The following is the result from benchmarking the serialization modules
included in the core Perl distribution (Storable and Data::Dumper) and
a couple of well-performing other modules. The 'StructureXS' module is
an XS bases Google ProtocolBuffers class.

The tested datastructure is available from 
  http://github.com/pmakholm/benchmark-serialize-perl/blob/e6263840439b7246c2b87a91b8db489c6eb80400/benchmarks/jvm-serializers/structure.pl
