Conclusion


Based on benchmark result with simple_orm_benchmark tool, Sequel has better performance than Active Record on every test cases. The biggest difference occurs in Eager Loading Query Per Association With 1-1 Records and Eager Loading Single Query With 1-1 Records with or without Transaction test cases. I still do not know why. I need to explore more about Sequel.
