NAME
Bencher::Scenario::DataUndump - Benchmark Data::Undump against eval() for loading a Data::Dumper output
VERSION
This document describes version 0.002 of Bencher::Scenario::DataUndump (from Perl distribution Bencher-Scenario-DataUndump), released on 2019-09-07.
SYNOPSIS
To run benchmark with default option:
% bencher -m DataUndump
To run module startup overhead benchmark:
% bencher --module-startup -m DataUndump
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.
