NAME
Bencher::Scenario::CloneModules::Startup - Benchmark startup of various data cloning modules
VERSION
This document describes version 0.051 of Bencher::Scenario::CloneModules::Startup (from Perl distribution Bencher-Scenarios-CloneModules), released on 2021-07-31.
SYNOPSIS
To run benchmark with default option:
% bencher -m CloneModules::StartupFor more options (dump scenario, list/include/exclude/add participants, list/include/exclude/add datasets, etc), see bencher or run bencher --help.
DESCRIPTION
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.
