Performance Through Parallelism: Java HotSpot Virtual Machine Garbage Collection Improvements
TS-1168
Presenter: John Coomes and Antonios Printezis, Sun Microsystems, Inc
This session covers recent improvements in garbage collection in the Java HotSpot virtual machine, with a particular focus on parallelism. It examines the parallel compacting collector, new in the JDK 6 release, and the concurrent mark sweep collector in depth, including a visual demonstration of the effects of parallelism (or lack thereof) on performance. It also presents future directions in garbage collection. Understanding the details of garbage collection can help Java technology developers make informed choices when deploying applications as well as answer the perennial question Why does GC take so long?
