Deep dive into the Eclipse OpenJ9 GC technologies

Day 2 /  / Track 3  /  EN / Hardcore. Really hard and demanding talk, you'll understand only if you're an experienced engineer.

Eclipse OpenJ9 is a Java Virtual Machine for OpenJDK that's optimized for small footprint, fast start-up, and high throughput. To help achieve these goals OpenJ9 provides 4 different GC policies that you may not know about. Each of these policies has its strengths and weaknesses so choosing the right one for your application can make a noticeable difference in performance and responsiveness. In this talk, we'll provide a deep dive into these technologies, explain how they work under the covers, the domains where they work best and discuss performance throughput versus responsiveness.
