Presentation Summary

23 years ago, the Java Virtual Machine promised to free programmers from the error-prone drudgery of memory management and the frustrations of maintaining code-bases for multiple operating systems. Alas, the large memory requirements and long start-up times of early JVM versions gave Java the reputation for being "slow." The reputation lingers despite Just-in-Time compilation and two decades of optimisation and performance-tuning. This presentation will focus on some of the most recent changes to the VM to trim down and speed up apps. We will also talk about the high-performance GraalVM that can support multiple languages at once. Depending on time/interest, we might also look at Quarkus.
