Oracle’s plans to modernise garbage collection in Java 9 have raised many questions. Uwe Schindler describes what exactly the G1 collector means for Java developers.
Alex Zhitnitsky is back to chat about java performance and debunking the stuff that you think you know about garbage collection. Read on for some serious trash-talking.
The performance tuning world is a dangerous place says Alex Zhitnitsky, who takes a look at how garbage collection affects java performance. Read on to understand what you’re up against, possible solutions and other alternatives available to you.
Why do traditional cache semantics sometimes struggles to scale, and what can we do about it?
Shenandoah, proposed to OpenJDK, can handle heaps larger than 100GB with sub-10ms pause times.
Ruben Badaro provides a crash course in monitoring garbage collection in production systems
If you wanna know what your garbage collector is up to, the best place to look is in the GC logs. That said, the GC logs are like any other ascii log file in that they can be full of 1000s of cryptic entries which make trying to figure out what the logs are saying without any tooling, a daunting task. In this session Kirk Pepperdine (Kodewerk Ltd) introduces Censum, a free tool designed to help you make sense out of your log files. Some of what Censum can tell you is if your JVM’s heap is misconfigured. For example, a large number of applications currently running in products systems are starved for memory, in at least one of their internal memory pools. But it’s not only starvation that can a cause of poor performance or long GC pauses. Too much memory can be equally

JAX London may have just gone, but the next JAX conference is already on the horizon, with JAX Germany scheduled to take place in Germany in May. At JAX Germany, creator of the Newspeak programming language Gilad Bracha will deliver a sessions on Newspeak and conduct a ‘Java Post Mortem.’JAXenter caught up with Gilad Bracha to learn more about what JAX Germany attendees can expect from his sessions…..
