Many modern applications and tools rely on Java. Yet, their startup time and time-to-peak performance remain challenging, especially for microservices and Kubernetes workloads that require fast scaling and responsiveness. Project Leyden, an ambitious OpenJDK initiative, aims to overcome these performance bottlenecks.

In this session, Ana and Moritz show how you can take advantage of Leyden’s optimizations using Java 25 and Spring Boot. You also get practical techniques you can apply today, along with a peek into the ongoing work inside Leyden and what that means for the performance of your Java application.
