A Visual Introduction to Inner-Workings of the JVM

Conference

Java Language

Room 1

Friday from 9:00 AM til 9:50 AM

Java developers are often exposed to the inner-workings of JVM's garbage collectors, and there are a host of tools that help monitor garbage collector activity.

But less often seen are the inner machinations of just-in-time compilation and deoptimization -- and how those machinations impact application performance.

In this talk, we'll learn how to read some of the JVMs mysterious log files, explore tools for visualizing the information, and most importantly correlate the JVM activity with application performance behavior.

Performance Issues JVM JIT

Douglas Hawkins
Doug is a lead JIT developer at Azul Systems where he's worked for the past 5 years. While at Azul, Doug has focused on performance trade-offs related to speculative optimizations and created ReadyNow: Azul's solution to Java's warm-up problems. In addition to working on JVMs, Doug worked previously as a Java developer for 10 years. This uncommon combination of experiences gives Doug an interesting view of Java from inside and out.
