NAME
Bencher::Scenario::StringFunctions::CommonPrefix - Benchmark calculating common prefix
VERSION
This document describes version 0.004 of Bencher::Scenario::StringFunctions::CommonPrefix (from Perl distribution Bencher-Scenarios-StringFunctions), released on 2021-07-30.
SYNOPSIS
To run benchmark with default option:
% bencher -m StringFunctions::CommonPrefixTo run module startup overhead benchmark:
% bencher --module-startup -m StringFunctions::CommonPrefixFor 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.
