Benchmark::Apps - Simple interface to benchmark applications.


This module provides a simple interface to benchmark applications (not necessarily Perl applications).

  use Benchmark::Apps;
  my $commands = {
       cmd1 => 'run_command_1 with arguments',
       cmd2 => 'run_command_2 with other arguments',
  my $conf = { pretty_print=>1, iters=>5 };
  Benchmark::Apps::run( $commands, $conf );


This module can be used to perform simple benchmarks on programs. Basically, it can be used to benchmark any program that can be called with a system call.



This method is used to run benchmarks. It runs the commands described in the hash passed as argument. It returns an hash of the results each command. A second hash reference can be passed to this method: a configuration hash reference. The values passed in this hash override the default behaviour of the run method. The configuration options available at this moment are:

When enabled it will print to stdout, in a formatted way the results of the benchmarks as they finish running. This option should de used when you want to run benchmarks and want to see the results progress as the tests run. You can disable it, so you can perform automated benchmarks.

Options: true (1) or false (0)

Default: false (0)

This is the number of iterations that each test will run.

Options: integer greater than 1

Default: 5

This is a reference to an anonymous function that will calculate the command argument based on the iteraction number.

Options: any function reference that returns a string

Default: empty function: always returns an empty string, which means no arguments will be given to the command


This method runs the commands described in the hash passed as argument. It returns an hash of the results and return codes for each command.


This method is used to print the final result to STDOUT before returning from the "run" method.


This method is not meant to be used directly, although it can be useful. It receives a command line and executes it via system, taking care of registering the elapsed time.
