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:

             Rate     MXMS       MS FP_Moose    FP_TT  TParams  Kavorka

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       MS  Kavorka    FP_TT
 MXMS       817/s       --     -92%     -95%     -98%     -98%     -98%
 FP_Moose 10353/s    1168%       --     -36%     -75%     -76%     -77%
 TParams  16236/s    1888%      57%       --     -61%     -63%     -64%
 MS       41684/s    5005%     303%     157%       --      -5%      -8%
 Kavorka  43689/s    5250%     322%     169%       5%       --      -4%
 FP_TT    45373/s    5457%     338%     179%       9%       4%       --

Kavorka, Function::Parameters+Type::Tiny, and Method::Signatures perform at comparable speed, clearly benefiting from the XSUB boost.
