Most of the Java garbage collection performance and tuning information available on the Internet and periodical tends to be very specific to either a garbage collector or specific to application symptoms. This presentation takes that myriad of information and boils it down to a set of fundamentals and principles. Coming …
The garbage-first (or G1) garbage collector is now an officially supported garbage collector in Java 7 update 4 and later VMs based on Oracle’s HotSpot. This session describes the operational basics of G1 and how to tune it.
The HotSpot JVM has been refined and revised with every release of the JDK since the advent of Java in the mid 90ies. Today, Java developers face an abundance of GC algorithms – from plain and simple serial stop-the-world collectors with a single reaper thread to highly parallelized collectors that …
This video dives deep into concurrency and garbage collection. It starts with a quick look at the next generation of serialization techniques, as well as implementation pitfalls around UUID. It also covers the internals of the memory model, and common garbage collection algorithms and their tuning knobs.
