Abstract

Scalability in Java web applications faces challenges in traditional concurrency models. This study compares two solutions: Spring Boot with virtual threads and Quarkus with reactive programming, evaluating their performance in blocking operations. Controlled tests show that each framework has distinct advantages – Spring in performance and Quarkus in stability. The choice between them should consider the specific requirements of the project, balancing efficiency and robustness for modern web applications.
