HotSpot promises to do wonders for us by Just-in-Time (JIT) compiling the “right” code for us, but how does it makes those decisions? And, perhaps more importantly, what happens when it’s wrong?
In this talk, you’ll learn through running Java code how the JVM decides to compile your code and see firsthand some situations where the JVM may get it wrong and have to deoptimize.
About the speaker
Doug Hawkins has been passionately developing software for over 10 years — creating applications for bioinformatics, finance, and online retail.
However, Doug’s true interest has always been exploring what goes inside the virtual machines that we use everyday.
To share that knowledge with others, Doug joined the No Fluff Just Stuff conference tour as a regular speaker 3 years ago. And two years ago, joined Azul Systems as a JVM Engineer working on Azul’s ReadyNow! technology.
