NAME¶
Dumbbench::Instance::PerlSub - Benchmarks a Perl code reference
SYNOPSIS¶
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();
# ...
DESCRIPTION¶
This class inherits from Dumbbench::Instance and implements benchmarking of Perl code references.
METHODS¶
new¶
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.
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.
code¶
Returns the code string that was set during construction.
dry_run_code¶
Returns the dry-run code string that was set during construction.
SEE ALSO¶
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.
