Philly ETE 2019 – Monica Beckwith – OpenJDK: In the New Age of Concurrent Garbage Collectors

Tags: , , , ,


Have you heard about the latest garbage collectors (GCs) in OpenJDK HotSpot VM? Are you interested in learning more about their algorithm and design goals? Would you like a basic comparison between them and the current default collector in OpenJDK? If you answered yes to any of the above questions, then this is the session for you!

In this session Monica Beckwith will talk about ZGC, Shenandoah GC and compare them to G1 GC (the current default GC).
