ABSTRACT:
Storage space within a heap may be subject to different types of garbage collection. A first type of garbage collection may be employed when there is a large amount of garbage in the heap, and the second type of garbage collection may be employed when there is a small amount of garbage in the heap. The computer system on which the heap is maintained may include intelligence for automatically deciding which of the garbage collection techniques to employ. The computer system may also automatically control when garbage collection is triggered by setting trigger points according to the amount of garbage collected in the most recent garbage collection. The trigger point may be decreased when there is a high amount of garbage collected, and the trigger point may be increased when there is a low amount of garbage collected.
