Jmix Data Performance Tests

This project demonstrates different approaches to saving data in Jmix framework and compares their performance.

The tests use the same model: Employee entity which has a few string, date and number attributes and a reference to the Department.

All tests save 10_000 new instances of the

entity.

See DataManagerTest, EntityManagerTest, JdbcTest classes.
