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.
SEE ALSO¶
Dumbbench, Dumbbench::Instance, Dumbbench::Instance::PerlEval, Dumbbench::Instance::PerlSub, Dumbbench::Result
Benchmark
Number::WithError does the Gaussian error propagation.
SOOT can optionally generate histograms from the timing distributions.
