=pod =encoding utf-8 =head1 DESCRIPTION Let's use L<Benchmark::Featureset::ParamCheck> to see how fast L<Type::Params> is compared with other modules for validating named parameters. (Hint: very fast.) =head1 RESULTS The results of running the script on a fairly low-powered laptop. Each parameter checking implementation is called 250,000 times. The table below displays the average time taken for each call in nanoseconds. =head2 With Type::Tiny::XS Type::Params .................................... 5079 ns (196850/s) Params::ValidateCompiler with Type::Tiny ........ 6599 ns (151515/s) Pure Perl Implementation with Ref::Util::XS ..... 7000 ns (142857/s) Naive Pure Perl Implementation .................. 7560 ns (132275/s) Data::Validator with Mouse ...................... 8440 ns (118483/s) Data::Validator with Type::Tiny ................. 9840 ns (101626/s) Params::ValidateCompiler with Moose ............. 11279 ns (88652/s) Params::ValidateCompiler with Specio ............ 11320 ns (88339/s) Data::Validator with Moose ...................... 18319 ns (54585/s) Params::Check with Type::Tiny ................... 21639 ns (46210/s) Params::Check with coderefs ..................... 28079 ns (35612/s) MooseX::Params::Validate with Moose ............. 48559 ns (20593/s) MooseX::Params::Validate with Type::Tiny ........ 54079 ns (18491/s) =head2 Without Type::Tiny::XS Pure Perl Implementation with Ref::Util::XS ..... 7120 ns (140449/s) Naive Pure Perl Implementation .................. 7520 ns (132978/s) Type::Params .................................... 7960 ns (125628/s) Data::Validator with Mouse ...................... 9000 ns (111111/s) Params::ValidateCompiler with Type::Tiny ........ 9159 ns (109170/s) Params::ValidateCompiler with Moose ............. 10159 ns (98425/s) Params::ValidateCompiler with Specio ............ 11240 ns (88967/s) Data::Validator with Type::Tiny ................. 14240 ns (70224/s) Data::Validator with Moose ...................... 18159 ns (55066/s) Params::Check with Type::Tiny ................... 22039 ns (45372/s) Params::Check with coderefs ..................... 22479 ns (44483/s) MooseX::Params::Validate with Moose ............. 42920 ns (23299/s) MooseX::Params::Validate with Type::Tiny ........ 43360 ns (23062/s) =head1 ANALYSIS Type::Params (using Type::Tiny type constraints) provides the fastest way of checking named parameters for a function, whether or not Type::Tiny::XS is available. Params::ValidationCompiler (also using Type::Tiny type constraints) is very nearly as fast. Params::ValidationCompiler using other type constraints is also quite fast, and when Type::Tiny::XS is not available, Moose and Specio constraints run almost as fast as Type::Tiny constraints. Data::Validator is acceptably fast. Params::Check is fairly slow, and MooseX::Params::Validate very slow. Type::Tiny::XS seems to slow down MooseX::Params::Validate for some strange reason. =head1 DEPENDENCIES To run this script, you will need: L<Module::Runtime>, L<Benchmark::Featureset::ParamCheck>. =head1 AUTHOR Toby Inkster E<lt>tobyink@cpan.orgE<gt>. =head1 COPYRIGHT AND LICENCE This software is copyright (c) 2017 by Toby Inkster.
