Monica Beckwith: Z Garbage Collector: Look Ma, ~No Pause!

Sep 23, 2021 · Manchester, United Kingdom

Are your application's tail-latencies holding it back from delivering its near-real time SLOs? Do your in-memory processing platform's long pauses only get worse with increasing heap sizes? How about those latency spikes causing variability in your end-to-end latency for your multi-tiered distributed systems?

If any of the above keep you up at night, then have no fear as Z Garbage Collector (GC) is here and is production ready in JDK 15.

In this talk, Monica Beckwith will cover the basics of Z GC and contrast it with G1 GC (the current default collector for OpenJDK JDK 11 LTS and tip).

Speaker: Monica Beckwith

Java Champion Monica Beckwith is considered a subject matter expert, has several published articles and gets regular invitations to give talks on JVM/JIT Compilation/Garbage Collection (GC). She is also a JavaOne Rock Star.

Monica has made various performance contributions to the Java HotSpot VM by identifying the need for a NUMA-aware allocator and allocation patterns, reduction of redundant instructions, reduction of the Java object header, prefetching patterns, redundant array checks in a loop and various other optimizations for the JIT compiler, the generated code, the JVM heuristics and garbage collection and collectors.

Prior to joining Microsoft, Monica was the JVM Performance Architect at Arm. Her past also includes leading Oracle’s Garbage First Garbage Collector performance team.

Meetup will be recorded and published on the MJC YouTube channel.
