Parallel and concurrent garbage collectors
In the last post, I’ve been talking about the basics of garbage collection and the generational garbage collector. While the generational garbage collector brought huge performance benefits by getting the large, old generation memory area to be infrequently visited by the collector, it still wasn’t enough for the new era of faster processors and memory sizes which spawned larger applications with multiple threads running concurrently, creating loads of garbage. The original generational collector was single threaded, and was called the serial collector. A parallel collector was required, and since the young and old generation memory spaces are different in the way the objects residing in them are used, so are the collectors implemented for them.
