复制算法的性能很优异，但是它有一个缺点是需要两倍于标记-清除收集器所需要的内存。
The copying algorithm has excellent performance characteristics, but it has the drawback of requiring twice as much memory as a mark-sweep collector.
新收集器中的两个——并行复制收集器和并发标记-清除收集器——设计为减少收集暂停时间。
Two of the new collectors are designed to reduce collection pause time — the parallel copying collector and the concurrent mark-sweep collector.
并行复制收集器和并发标记-清除收集器基本上是默认的复制收集器和标记-整理收集器的并发版本。
The parallel copying collector and concurrent mark-sweep collector are basically concurrent versions of the default copying and mark-compact collectors.
JD K 1.2及以后版本所使用的分代垃圾收集器提供了比早期JDK所使用的标记-清除-整理收集器好得多的分配和收集性能。
The generational collector employed by JDK 1.2 and later offers far better allocation and collection performance than the mark-sweep-compact collector used by earlier JDKs.
它采用了一种延迟引用计数（Deferred Reference Counting，DRC）机制，并结合一个增量的、保守的标记/清除收集器。
This is a Deferred Reference Counting (DRC) mechanism combined with an incremental, conservative mark/sweep collector.
