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

Haha! I'm pretty sure AOT Cache would also work on a Spring AI project!

Meet the Spring Team Come meet the Spring team! This year at Devoxx, many maintainers, advocates and contributors will be at the conference, and we’re delighted to meet with our users and members of the community. In this “open mic” session, you’ll have the opportunity to ask us anything about the various Spring projects, our current efforts and ideas for the future, and of course, the soon-to-be-released new generation with Boot 4 and Framework 7.

Yes, we have a 9.6 kWh battery in the basement.

I've got this setup since March, and I haven't bought any power from the grid since then. But the simulation I've run said that in the winter months I'm going to buy electricity again, because then the heat pump is kicking in.
