PURPOSE

Benchmarking the following method call defined with several different modules:

        method foo ( Int $x, ArrayRef[Int] $y ) {
                return [ $x, $y ];
        }

Modules tested are:

• Kavorka (of course)

• Type::Params (not as sugary, but probably the fastest pure Perl method signature implementation on CPAN)

• Function::Parameters plus Moose type constraints

• Function::Parameters plus Type::Tiny type constraints

• Method::Signatures

• MooseX::Method::Signatures

RESULTS

Standard Results

Running perl -Ilib examples/benchmarks.pl:

Kavorka is the winner.

Any::Moose + Mouse Results

If Any::Moose is loaded before Moose, then Method::Signatures will be able to use Mouse's type constraints instead of Moose's. Also, if Mouse is loaded before a Type::Tiny type constraint has been checked, Type::Tiny can sometimes use Mouse's XSUBs to accelerate itself.

Running perl -mAny::Moose -Ilib examples/benchmarks.pl:

             Rate     MXMS FP_Moose  TParams  Kavorka    FP_TT       MS
 MXMS       798/s       --     -92%     -95%     -98%     -98%     -98%
 FP_Moose 10083/s    1163%       --     -37%     -73%     -74%     -75%
 TParams  15937/s    1897%      58%       --     -58%     -59%     -60%
 Kavorka  37716/s    4626%     274%     137%       --      -3%      -5%
 FP_TT    38862/s    4770%     285%     144%       3%       --      -2%
 MS       39656/s    4869%     293%     149%       5%       2%       --

Kavorka is not as fast as the Function::Parameters + Type::Tiny combination, and Method::Signatures comes out at the front of the pack.

But Kavorka still performs well, and clearly benefits from the XSUB boost.
