DESCRIPTION

Let's use Benchmark::Featureset::ParamCheck to see how fast Type::Params is compared with other modules for validating positional 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) is the fastest framework for checking positional parameters for a function, whether or not Type::Tiny::XS is available.

The only way to beat it is to write your own type checking in longhand, but if Type::Tiny::XS is installed, hand-rolled code might still be slower.

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 and MooseX::Params::Validate are far slower.

Type::Nano is slow. (But it's not written for speed!)

DEPENDENCIES
