Older-first garbage collection in practice: evaluation in a Java Virtual Machine

Stefanovic, Darko; Hertz, Matthew; Blackburn, Stephen; McKinley, Kathryn; Moss, J Eliot B


Until recently, the best performing copying garbage collectors used a generational policy which repeatedly collects the very youngest objects, copies any survivors to an older space, and then infrequently collects the older space. A previous study that used garbage-collection simulation pointed to potential improvements by using an Older-First copying garbage collection algorithm. The Older-First algorithm sweeps a fixed-sized window through the heap from older to younger objects, and avoids...[Show more]
