Dumbbench::Instance::Cmd - Benchmarks an external command
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(); # ...
This class inherits from Dumbbench::Instance and implements benchmarking of external commands.
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).
Dumbbench::Instance::Cmd
command
system
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.
dry_run_command
Returns the command that was set on object construction.
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.
