Re-Revisiting Performance in Ruby 3.4.1
- The article discusses revisiting performance in Ruby 3.4.2 and addresses feedback received on a previous article focusing on the usage of Structs and Classes.
- Initial observations favored Structs over Classes in some scenarios, but further benchmarking revealed that Classes are now faster than Structs in most cases.
- Benchmarking code from the Alchemist's article was used to compare performance between different data structures like Arrays, Hashes, Classes, Structs, and Data.
- Results showed that in real-life scenarios, Classes outperformed Structs, with Data objects being more performant than both when dealing with 10 attributes.
- Stringified Hashes were noted to perform well under the frozen string literal comment, and using primitive data objects like Arrays and Hashes is recommended for larger datasets.
- The article emphasized that Structs and Data objects serve as value objects, allowing for direct comparison, unlike Class instances.
- The conclusion highlights the performance priority order of data structures and advises using frozen string literal comments and prioritizing Arrays or Hashes for larger datasets.
