Dumbbench::Instance::PerlSub - Benchmarks a Perl code reference
use Dumbbench; my $bench = Dumbbench->new( target_rel_precision => 0.005, # seek ~0.5% initial_runs => 20, # the higher the more reliable ); $bench->add_instances( Dumbbench::Instance::PerlSub->new(name => 'mauve', code => sub {...}), # ... more things to benchmark ... ); $bench->run(); # ...
This class inherits from Dumbbench::Instance and implements benchmarking of Perl code references.
Constructor that takes named arguments.
In addition to the properties of the base class, the Dumbbench::Instance::PerlSub constructor requires a code parameter. The code needs to be subroutine reference.
Dumbbench::Instance::PerlSub
code
Optionally, you can provide a dry_run_code option. It has the same structure and purpose as the code option, but it is used for the dry-runs. By default, an empty sub is used for this, so it's unlikely you will need the dry-run unless you want to strip out some particular overhead.
dry_run_code
Returns the code string that was set during construction.
Returns the dry-run code string that was set during construction.
Dumbbench, Dumbbench::Instance, Dumbbench::Instance::PerlEval, Dumbbench::Instance::Cmd, Dumbbench::Result
Benchmark
Number::WithError does the Gaussian error propagation.
SOOT can optionally generate histograms from the timing distributions.
