NAME Bencher::Scenario::strftimeq - Benchmark strftimeq() routines VERSION This document describes version 0.001 of Bencher::Scenario::strftimeq (from Perl distribution Bencher-Scenario-strftimeq), released on 2019-11-20. SYNOPSIS To run benchmark with default option: % bencher -m strftimeq To run module startup overhead benchmark: % bencher --module-startup -m strftimeq 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.
