NAME
Bencher::Scenario::LoggingModules::NullLogging - Benchmark logging statement that does not output anywhere (to measure logging overhead)
VERSION
This document describes version 0.004 of Bencher::Scenario::LoggingModules::NullLogging (from Perl distribution Bencher-Scenarios-LoggingModules), released on 2021-04-09.
SYNOPSIS
To run benchmark with default option:
% bencher -m LoggingModules::NullLogging
For 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.

BENCHMARK NOTES
You might notice that Log::ger+Log::ger::Plugin::OptAway (LGP:OptAway) is slower than plain Log::ger at 100k trace. This is because the plugin loading and setup overhead eclipses the gain provided by the OptAway plugin. If you try the these not-included-by-default participants they will show the benefit of OptAway:
Log::ger-1mil_log_trace
Log::ger+LGP:OptAway-1mil_log_trace
