2023 - Bartłomiej Żyliński - VM Under The Hood

Have you ever wondered how JVM works under the hood?

In my talk, I focus on the inner working of JVM itself and JVM compilation process in particular.

I will open with a short description of what compilation is, bring closer concept of tiered compilation, and describe what HotSpot means in terms of JVM. I will also mention Graal VM and its impact on the JVM ecosystem.

Please mind that this is a basic level talk that revolves around how JVM works and I will not be sharing tips & tricks around JVM performance.
