NAME
Bencher::Scenario::LogGer::OutputStartup
VERSION
This document describes version 0.018 of Bencher::Scenario::LogGer::OutputStartup (from Perl distribution Bencher-Scenarios-LogGer), released on 2021-04-09.
SYNOPSIS
To run benchmark with default option:
% bencher -m LogGer::OutputStartupTo run module startup overhead benchmark:
% bencher --module-startup -m LogGer::OutputStartupFor 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.
