Spring Boot applications, with their opinionated configuration, may experience slower startup times due to default configurations for libraries and services.
To improve startup times, lazy initialization of beans can be enabled using the spring.main.lazy-initialization property.
Reducing unnecessary dependencies or using profiles to load only required beans can also help in optimizing startup times.
Spring Boot applications, with their numerous dependencies, may consume more memory than necessary, often becoming an issue for large-scale applications or resource-constrained environments.
