However this collector parallelizes the copying collection over multiple threads, which is more efficient than the original single-thread copying collector for multi-CPU machines (though not for single-CPU machines). This algorithm potentially speeds up young generation collection by a factor equal to the number of CPUs available, when compared to the original singly-threaded copying collector. The parallel scavenge collector (Enabled using -XX:UseParallelGC). This is like the previous parallel copying collector, but the algorithm is tuned for gigabyte heaps (over 10GB) on multi-CPU machines. This collection algorithm is designed to maximize throughput while minimizing pauses. It has an optional adaptive tuning policy which will automatically resize heap spaces. If you use this collector, you can only use the the original mark-sweep collector in the old generation (i.e. the newer old generation concurrent collector cannot work with this young generation collector). >> > >> > How can I set this parameters? >> > >> > >> > Thanks for your help. >> > >> > Regards >> >> >> >> -- >> Claus Ibsen >> ----------------- >> Red Hat, Inc. >> Email: cib...@redhat.com >> Twitter: davsclaus >> Blog: http://davsclaus.com >> Author of Camel in Action: http://www.manning.com/ibsen >> Make your Camel applications look hawt, try: http://hawt.io >>
