最后，还有混合型的收集器，如1.2和以后版本的JDK使用的分代收集器，它对堆的不同区域使用不同的收集算法。

Finally, there are hybrid collectors, such as the generational collector employed by the 1.2 and later JDKs, which use different collection algorithms on different areas of the heap.

分代垃圾收集器把堆分成多代；多数JVM使用两代，“年轻代”和“年老代”。

A generational garbage collector divides the heap into multiple generations; most JVMs use two generations, a "young" and an "old" generation.

其他性能改进方法包括提高堆大小、调整保育室(nursery)大小(用于分代收集器)和尝试另一个GC策略。

Performance can also be improved by increasing the heap size, playing with the nursery size (for generational collectors), and trying a different GC policy.
