NAME

Bencher::Scenario::Example::NameAndSeq - Participant/dataset with name that is also a sequence number

VERSION

This document describes version 0.002 of Bencher::Scenario::Example::NameAndSeq (from Perl distribution Bencher-Scenarios-Examples), released on 2017-01-25.

SYNOPSIS

To run benchmark with default option:

 % bencher -m Example::NameAndSeq

To run module startup overhead benchmark:

 % bencher --module-startup -m Example::NameAndSeq

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.
