What if we could drastically improve the JVM startup time? What if we could start a Kotlin-powered backend in milliseconds? Let's explore some exciting new JVM features like the experimental CRaC (Coordinated Restore at Checkpoint) and JEP 483 (Ahead-of-Time Class Loading & Linking) from Project Leyden, a feature of JDK 24! How fast are they, and how are they different from GraalVM and Kotlin Native? Plus, let's have a look at JEP 515 (Ahead-of-Time Method Profiling) from the brand new JDK 25! Finally, let's go completely wild, and experiment with a crazy idea: Let's see if we can apply these technologies to make our Gradle unit test workflows in Android projects faster as well!
