NAME

Bencher::Scenario::TruncatingString - Benchmark modules that truncate/elide string

VERSION

This document describes version 0.001 of Bencher::Scenario::TruncatingString (from Perl distribution Bencher-Scenario-TruncatingString), released on 2019-09-11.

SYNOPSIS

To run benchmark with default option:

            

              
              
% bencher -m TruncatingString
            
          

To run module startup overhead benchmark:

            

              
              
% bencher --module-startup -m TruncatingString
            
          

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.
