You think you know all there is about building apps for the JVM. You've used all the cool tools. You've written your own persistence library or web frameworks. Maybe you've even implemented a JVM language. But do you really know what happens to your code after you hand it off to the JVM? This talk will explore the guts of the OpenJDK VM, Hotspot. We'll take a few simple examples from bytecode through optimization and compilation all the way down to assembly code, and learn how you can ensure your code runs as fast as possible.
