What are the default settings for the concurrent low pause collector?
Garbage Collection - Frequently Asked QuestionsThe default heap size for the concurrent low pause collector is the same as for the default collector. The other parameters are set a described below. These setting have been shown to work well for an application that has mostly very short lived data plus some data that is very long lived. Some of the options require a computation which is enclosed in angle brackets (<>), of which two depend on the number of cpus on the machine (#cpus.
Related QuestionsWhat are the phases of the concurrent low pause collector?
Garbage Collection - Frequently Asked QuestionsPhase 1 (Initial Checkpoint) involves stopping all the Java threads, marking all the objects directly reachable from the roots, and restarting the Java threads. Phase 2 (Concurrent Marking) starts scanning from marked objects and transitively marks all objects reachable from the roots. The mutators are executing during the concurrent phases 2, 3, and 5 below and any objects allocated in the CMS generation during these phases (including promoted objects) are immediately marked as live.

Related QuestionsWhy does the low pause collector sometimes do more collections than the default collector?
Garbage Collection - Frequently Asked QuestionsIf you are not seeing major collections with the default collector but are seeing many major collections with the concurrent low pause collector, you are probably seeing some type of fragmentation problem. Try using a larger heap with the concurrent low pause collector.
Related QuestionsWhy is fragmentation a potential problem for the concurrent low pause collector?
Garbage Collection - Frequently Asked QuestionsNormally the concurrent low pause collector does not copy nor compact the live objects. A garbage collection is done without moving the live objects. If fragmentation becomes a problem, allocate a larger heap. In 1.4.2 if fragmentation in the tenured generation becomes a problem, a compaction of the tenured generation will be done although not concurrently. In 1.4.1 that compaction will occur if the UseCMSCompactAtFullCollection option is turned on.
Related QuestionsWhy is the startup with the concurrent low pause (CMS) collector slow?
Garbage Collection - Frequently Asked QuestionsWith CMS (+XX:UseConcMarkSweepGC) you sometimes need to set the minimum and maximum heap size to the same value (or at least set a large minimum value) because CMS sometimes spends time early growing its heap. This may also be true of the perm generation. Try a larger perm generation size using the options -XX:PermSize=<initial size> -XX:MaxPermSize=<maximum size>.
Related QuestionsWith the concurrent low pause collector how can I tell how much floating garbage is left?
Garbage Collection - Frequently Asked QuestionsBecause the application threads and the GC thread run concurrently, an object that is live at the beginning of a collection and which the GC thread has marked as live may die by the end of the collection. Such objects are referred to as floating garbage. The amount of floating garbage can be inferred if a full compacting collection occurs immediate following a concurrent collection. Any reduction in the heap size is due to floating garbage.
Related QuestionsWhy does fragmentation occur with the concurrent low pause collector?
Garbage Collection - Frequently Asked QuestionsThe concurrent low pause collector normally does not move objects during a garbage collection. Fragmentation occurs when live objects are interspersed with the free space left as the result of the collection. The exception is when a non-concurrent, full collection occurs. In this latter case the applications is stopped during the collection and the live objects are compacted to one end of the generation and all the free space reside in a single contiguous piece.
