对特定类型的应用来说，这是很有帮助的。例如，我曾经见到有的电子商务网站具有非常大的堆空间，其中包含了大约40G的字符串数据。Java 9的ompact Strings技术能够将这种类型的内存使用减半。这反过来又会对GC的性能带来积极的影响。对于有些应用来说（这可能就包括大型的Solr安装环境及类似场景），单单这一项收益就值得将运行时升级到Java 9。
这项变更是很重要的，因为相对于Parallel来说，G1会在应用线程上做更多的事情，而Parallel几乎没有在应用线程上做任何事情，它基本上完全依赖GC线程完成所有的内存管理。这意味着切换到G1将会为应用线程带来额外的工作，从而直接影响到应用的性能。 在很多（甚至可以说大多数）场景中，这种额外的性能损耗都不是什么问题。但是，在这方面，我确实也曾经见过从Parallel切换到G1时，有一定比例的工作负载会引起性能的下降。对于这些应用来说，这种性能下降是无法接受的，所以他们无法切换至G1收集器。随着G1成为默认的收集器，这将会影响到升级至Java 9的每个应用。
