AOT Computation in Java for Faster Startup 🚀

About this video

In recent years, application startup and warmup have become increasingly important metrics when evaluating an application's overall performance. Project Leyden seeks to address these concerns by creating an Ahead-of-Time Cache the JVM can use to improve startup and warmup. In this video, Billy explains how ACME Soft hopes to incorporate Ahead-of-Time computation into their development lifecycle.
