I was working on another email part of my Modern Ruby Email Course so I did some benchmarks on `Data.define` vs `Struct` vs `OpenStruct`
- When creating new objects, Struct is the fastest, Open Struct the slowest
- When accessing attributes, Data(dot)define is slightly faster
Accessing attributes
This time `Data.define` is maybe the fastest one but there is not a signifiant difference to `Struct`. On the other side `OpenStruct` is almost twice as slow.
I run this on my local machine:
• Apple M3 PRO
• 36 GB
• Running Mac OS 14.4 (23E214)
• Ruby 3.3.0
You can explore the repo with the code that I run and all the resources at https://github.com/lucianghinda/value-object-in-ruby-benchmarks
And I published an article with all these findings at https://allaboutcoding.ghinda.com/micro-benchmarking-value-objects-in-ruby-datadefine-vs-struct-vs-openstruct
