Dumbbench::Instance::Cmd(3p)

NAME
Dumbbench::Instance::Cmd - Benchmarks an external command

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::Cmd->new(name => 'mauve', command => [qw(perl -e 'something')]),
    # ... more things to benchmark ...
  );
  $bench->run();
  # ...

DESCRIPTION
This class inherits from Dumbbench::Instance and implements benchmarking of external commands.

METHODS

  new
Constructor that takes named arguments.

In addition to the properties of the base class, the "Dumbbench::Instance::Cmd" constructor requires a "command" parameter. "command" can either be string specifying the external command with its options or (preferably) a reference to an array of command-name and options (as with the ordinary "system" builtin).

Optionally, you can provide a "dry_run_command" option. It has the same structure and purpose as the "command" option, but it is used for the dry-runs. If "dry_run_command" is not specified, the dry-run will consist of starting another process that immediately exits.

  command
Returns the command that was set on object construction.

  dry_run_command
Returns the command that was set for dry-runs on object construction.

Benchmark

Number::WithError does the Gaussian error propagation.

SOOT can optionally generate histograms from the timing distributions.
