'Spring java API extremely slow using JPA to save a json object

I'm having trouble using jpa to save an object, heres and example of how its saved:

public void saveMyCatalog(TheEntity entity) {
    storeCatalogRegistrationRepository.save(entity);
}

Googling it I found that the method saveAll() could be faster, but in my case my request is not a list of objects, but instead, is a object inside other, with a lot of lists. I cant really share the objects because of compliance reasons, so I hope you guys can help me with this much of information.

My question is, how can I save a object with a lot of nested lists faster using jpa?
