NAME

Bencher::Scenario::URIEscaping - Benchmark URI escaping using various modules

VERSION

This document describes version 0.006 of Bencher::Scenario::URIEscaping (from Perl distribution Bencher-Scenario-URIEscaping), released on 2020-06-18.

SYNOPSIS

To run benchmark with default option:

 % bencher -m URIEscaping

To run module startup overhead benchmark:

 % bencher --module-startup -m URIEscaping

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 NOTES

URI::Encode::XS is the fastest, but it does not support custom list of safe characters. If you don't want to encode / as %2F, for example, you're out of luck. For URI escaping with custom character list support, the fastest is URI::XSEscape followed by URI::Escape::XS.
