Thank you to everyone who joined our session on boosting Java performance with Project Leyden, Java 25, and Spring Boot! 🚀

@0.5ritter.de and I hope that you will apply the optimizations and tips we shared today. The slides we used:

Supercharge your JVM performance with Project Leyden and Spring Boot

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 showed how you can take advantage of Leyden’s optimizations using Java 25 and Spring Boot. You also got 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. - Download as a PDF or view online for free

Please don’t use AI to write PR descriptions.
They add noise, not clarity.

A few honest sentences in your own words > a generic wall of text. Code quality speaks loudest.
