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. BENCHMARKED MODULES Version numbers shown below are the versions used when running the sample benchmark.
