This article explains how to use the Benchmark module in Ruby to measure and report execution time for code snippets. It includes examples of different benchmarking methods and how to interpret the results. Instructions for installation and contribution to the module are also provided.

The article discusses the challenges of using regular expressions for data extraction in Ruby, particularly highlighting the performance issues with the default Onigmo engine. It compares alternative regex engines like re2, rust/regex, and pcre2, presenting benchmark results that demonstrate the superior speed of rust/regex, especially in handling various text cases and complexities.
