Various GC Collectors

Collector	Function	Recommended for	How to enable
Serial Collector	Uses single thread for both minor and major collections. Simplest.	Single processor machines	-XX:+UseSerialGC
Parallel Collector (Throughput Collector)	Uses multiple threads for minor collection.	Multi processor machines, enterprise class applications	-XX:+UseParallelGC To enable Major parallel collection, add -XX:+UseParallelOldGC
CMS Collector (Concurrent Mark and Sweep Collector)	Mostly performs GC simultaneously along with Application	Applications that cannot tolerate longer GC pause times	-XX:+UseConcMarkSweepGC
G1 Collector	Strives to collect from Heap regions that have the most garbage	Most enterprise class applications. Through testing required before implementing.	–XX:+UseG1GC
