       But there are in fact <10>...

💣 You may have even more select statements with production data.
Be careful with the cost of JDBC roundtrips: https://blog.jooq.org/2017/12/18/the-cost-of-jdbc-server-roundtrips/

Auto-detection of Hibernate and Spring Data JPA:

💡 Perhaps you are facing an N+1 select issue
	* With Hibernate, you may fix it by using JOIN FETCH
	                                       or LEFT JOIN FETCH
	                                       or FetchType.LAZY
	                                       or ...
	* With Spring Data JPA, you may fix it by adding @EntityGraph(attributePaths = { "..." })
      	  on repository method: https://docs.spring.io/spring-data/jpa/docs/current/reference/ht
