NAME

Bencher::Scenario::FileWhichCached - Benchmark File::Which::Cached

VERSION

This document describes version 0.001 of Bencher::Scenario::FileWhichCached (from Perl distribution Bencher-Scenario-FileWhichCached), released on 2019-06-08.

SYNOPSIS

To run benchmark with default option:

 % bencher -m FileWhichCached

To run module startup overhead benchmark:

 % bencher --module-startup -m FileWhichCached

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.
