Ahead of time, the final frontier

There are many initiatives inside the OpenJDK that are revolutionizing the way our Java applications behave. Project Leyden accelerates peak performance by improving ahead of time caching. But, do you know how to use it with your application?

On this session we will discuss what Leyden is, what is the state of art of the ahead of time cache, and showcase a few examples. We will prove (with potential demo effect!) that Leyden decreases warm-up time, and present the tools you can use to optimize your application!

Quarkus Insights #230: Hypercharging Java with Leyden Upcoming

Heard about Leyden? This revolutionary OpenJDK project is all about accelerating warmup time and boosting peak performance. But did you know you can already start using it, especially with your Quarkus apps? Join us for Quarkus Insights # 230, as we explore what Leyden is, the current state of ahead-of-time caching, and see some cool Quarkus examples!
