NAME

Bencher::Scenario::MemoryCacheModules::Startup - Benchmark startup overhead of memory cache modules

VERSION

This document describes version 0.001 of Bencher::Scenario::MemoryCacheModules::Startup (from Perl distribution Bencher-Scenarios-MemoryCacheModules), released on 2018-06-19.

SYNOPSIS

To run benchmark with default option:

% bencher -m MemoryCacheModules::Startup

To run module startup overhead benchmark:

% bencher --module-startup -m MemoryCacheModules::Startup

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.
