Dumbbench::Instance::PerlEval(3)

NAME
Dumbbench::Instance::PerlEval - Benchmarks a string of Perl code

SYNOPSIS
  use Dumbbench;

  my $bench = Dumbbench->new(
    target_rel_precision => 0.005, # seek ~0.5%
    initial_runs         => 20,    # the higher the more reliable
  );
  $bench->add_instances(
    Dumbbench::Instance::PerlEval->new(name => 'mauve', code => 'for(1..1e9){$i++}'),
    # ... more things to benchmark ...
  );
  $bench->run();
  # ...

DESCRIPTION
This class inherits from Dumbbench::Instance and implements benchmarking of strings of Perl code using "eval """.

METHODS

  new
Constructor that takes named arguments.

In addition to the properties of the base class, the "Dumbbench::Instance::PerlEval" constructor requires a "code" parameter. The "code" needs to be a string that is suitable for passing repeatedly to string-"eval".

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, a simple "eval" is used for this, so it's unlikely you will need the dry-run unless you want to strip out the compile-time overhead of your code.

  code
Returns the code string that was set during construction.

  dry_run_code
Returns the dry-run code string that was set during construction.

Benchmark

Number::WithError does the Gaussian error propagation.

SOOT can optionally generate histograms from the timing distributions.
