NAME
Bencher::Scenario::CBlocks::Numeric - Benchmark numeric performance of C::Blocks
VERSION
This document describes version 0.003 of Bencher::Scenario::CBlocks::Numeric (from Perl distribution Bencher-Scenarios-CBlocks), released on 2017-07-03.
SYNOPSIS
To run benchmark with default option:
% bencher -m CBlocks::NumericTo run module startup overhead benchmark:
% bencher --module-startup -m CBlocks::NumericFor more options (dump scenario, list/include/exclude/add participants, list/include/exclude/add datasets, etc), see bencher or run bencher --help.
DESCRIPTION
Each code generates random number (the perl participant using pure-perl code.
Packaging a benchmark script as a Bencher scenario makes it convenient to include/exclude/add participants/datasets (either via CLI or Perl code), send the result to a central repository, among others . See Bencher and bencher (CLI) for more details.
