NAME

Bencher::Scenario::PerinciCmdLine::ResultStream - Benchmark result stream vs raw Perl I/O

VERSION

This document describes version 0.03 of Bencher::Scenario::PerinciCmdLine::ResultStream (from Perl distribution Bencher-Scenarios-PerinciCmdLine), released on 2017-01-25.

SYNOPSIS

To run benchmark with default option:

% bencher -m PerinciCmdLine::ResultStream

For more options (dump scenario, list/include/exclude/add participants, list/include/exclude/add datasets, etc), see bencher or run bencher --help.

DESCRIPTION

Conclusion: about 2.5 times slower on my PC (1.2mil lines/sec vs 3mil).

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.
