Using springboot+JPA，the first time to save is too slow

I used springboot+JPA+Hibernate to insert data. But the insertion speed of the first data is too slow, and it becomes faster later. I want to eliminate this situation and make all data insertions fast, including the first one. Is there any way to achieve this? Perhaps it can be achieved through configuration changes or some initialization operations. Below are my configurations, all the test code, and test result. And I have uploaded them to GitHub[https://github.com/MayflyShake/heart-test].
