Java Concurrent Mark and Sweep Collector

Internal

• Java Garbage Collection

Overview

The Concurrent Mark Sweep (CMS) collector, is also referred to as the concurrent low pause collector. It only collects the old generation. The main reason to use it is to minimaze the "stop-the-world" pauses by doing most of the garbage collection work concurrently with the application threads. Normally the concurrent low pause collector does not move, copy or compact the live objects.
