# DefNew 与 ParNew [HotSpot VM的开发历史](https://hllvm-group.iteye.com/group/topic/37095) ``` HotSpot VM的GC组老人之一Jon Masamitsu很久之前就写过blog讲解这个：https://blogs.oracle.com/jonthecollector/entry/our_collectors 简单来说，有这么多东西反映了HotSpot VM的开发历史和实现细节。我在写篇东西讲述这部分历史，哪天写完的话在这边也放个链接嗯。 DefNewGeneration是default new generation ParNewGeneration是parallel new generation 原本HotSpot VM里没有并行GC，当时就只有NewGeneration；后来准备要加入young gen的并行GC，就把原本的NewGeneration改名为DefNewGeneration，然后把新加的并行版叫做ParNewGeneration。 这些XXXGeneration都在HotSpot VM的“分代式GC框架”内。本来HotSpot VM鼓励开发者尽量在这个框架内开发GC，但后来有个开发就是不愿意被这框架憋着，自己硬写了个没有使用已有框架的新并行GC，并拉拢性能测试团队用这个并行GC来跑分，成绩也还不错，于是这个GC就放进HotSpot VM里了。这就是我们现在看到的ParallelScavenge。 （结果就是HotSpot GC组不得不维护两个功能几乎一样、但各种具体细节不同的并行GC。其实是件很头疼的事情嗯） Scavenge或者叫scavenging GC，其实就是copying GC的另一种叫法而已。HotSpot...
