NAME

Bencher::Scenario::SprintfVsUnpack - Benchmark sprintf() vs unpack()

VERSION

This document describes version 0.001 of Bencher::Scenario::SprintfVsUnpack (from Perl distribution Bencher-Scenario-SprintfVsUnpack), released on 2017-04-16.

SYNOPSIS

To run benchmark with default option:

 % bencher -m SprintfVsUnpack

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.

BENCHMARK PARTICIPANTS

• sprintf (perl_code)

  Code template:

   state $data = <sprintf_data>; my $res; for (1..1000) { $res = sprintf(<sprintf_fmt>, $data) } $res

• unpack (perl_code)

  Code template:

   state $data = chr(<unpack_data>); my $res; for (1..1000) { $res = unpack(<unpack_fmt>, $data) } $res

BENCHMARK DATASETS

• binary-byte
