DESCRIPTION

Let's use Benchmark::Featureset::ParamCheck to see how fast Type::Params is compared with other modules for validating named parameters. (Hint: very fast.)

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.

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.

DEPENDENCIES

To run this script, you will need:

Module::Runtime, Benchmark::Featureset::ParamCheck.
