NAME
Bencher::Scenario::PerinciCmdLine::InputStream - Benchmark input stream vs raw Perl I/O
VERSION
This document describes version 0.03 of Bencher::Scenario::PerinciCmdLine::InputStream (from Perl distribution Bencher-Scenarios-PerinciCmdLine), released on 2017-01-25.
SYNOPSIS
To run benchmark with default option:
% bencher -m PerinciCmdLine::InputStreamFor more options (dump scenario, list/include/exclude/add participants, list/include/exclude/add datasets, etc), see bencher or run bencher --help.
DESCRIPTION
1mil lines input data, short line ("1"), each line is chomped.
Conclusion: about 4.7 times slower on my PC (1.6mil lines/sec vs 7.5mil).
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.
