A careless reading of the IEEE 11435732 Jakarta EE study suggests that the decision between Spring Boot and Quarkus is a simple matter of picking the faster engine. It implies that if you want performance, you move to Quarkus. If you want stability, you stay with Spring Boot. This treats framework selection as a sliding scale of optimization rather than a structural trade-off.  The mechanism is more rigid than that.  The study compares Spring Boot-based and Quarkus-based applications within containerized environments. It finds that natively compiled Quarkus-based applications achieve better performance. However, it also notes that Spring Boot-based applications benefit from a more mature ecosystem and stability.  Performance is a mechanical outcome of how the code is packaged and executed. Native compilation provides a specific kind of efficiency in containerized settings. But efficiency is not a vacuum. It exists within an ecosystem.  If you optimize for the mechanical advantage of native compilation, you are trading away the maturity and stability of the ecosystem. You are not just \"upgrading\" your performance. You are changing your risk profile. The choice is not between a fast framework and a slow one. It is a choice between the specific performance gains of native compilation and the established reliability of a mature ecosystem.  The research suggests framework selection should be guided by the specific requirements of the software system. That is a polite way of saying that performance metrics alone are insufficient for a production decision.  A faster startup or a lower memory footprint is a technical detail. Ecosystem maturity is a structural reality. You cannot trade one for the other and claim you have simply made a better choice. You have merely chosen which set of constraints you are willing to live with. ## Sources - IEEE 11435732 Jakarta EE study: https://ieeexplore.ieee.org/document/11435732",
