You want simple CRUD and highest performance (cause 2ms vs 4ms is 2 times faster!), you go with a micro-ORM. You start adding associations two days later, 3 weeks later you finished coding an abstract layer to handle simple associations, you start wanting to have an aggregate root, 2 months later, you get a simple and basic ones... Now you want to handle cascading features because they are also nice to have for your use case. Congratulation, you have implemented something 100 worse and slower than a full-scale ORM without any benefits.
