1.8em;letter-spacing: 0em;text-indent: 0em;padding-top: 8px;padding-bottom: 8px;">G1 是一款非常优秀的垃圾收集器，不仅适合堆内存大的应用，同时也简化了调优的工作。通过主要的参数初始和最大堆空间、以及最大容忍的 GC 暂停目标，就能得到不错的性能；同时，我们也看到 G1 对内存空间的浪费较高，但通过<strong style="color: rgb(0, 0, 0);background-attachment: scroll;background-clip: border-box;background-image: none;background-origin: padding-box;background-position: 0% 0%;background-repeat: no-repeat;background-size: auto;width: auto;height: auto;border-style: none;border-width: 3px;border-color: rgba(0, 0, 0, 0.4);border-radius: 0px;">首先收集尽可能多的垃圾</strong>(Garbage First)的设计原则，可以及时发现过期对象，从而让内存占用处于合理的水平。</p> <p data-tool="mdnice编辑器" style="color: rgb(20, 20, 20);line-height: 1.8em;letter-spacing: 0em;text-indent: 0em;padding-top: 8px;padding-bottom: 8px;">虽然 G1 也有类似 CMS 的收集动作：初始标记、并发标记、重新标记、清除、转移回收，并且也以一个串行收集器做担保机制，但单纯地以类似前三种的过程描述显得并不是很妥当。</p> <ul data-tool="mdnice编辑器" style="margin-top: 8px;margin-bottom: 8px;padding-left: 25px;" class="list-paddingleft-1"> <li> <section style="margin-top: 5px;margin-bottom: 5px;color: rgb(20, 20, 20);line-height: 1.8em;letter-spacing: 0em;"> G1 的设计原则是"<strong style="color: rgb(0, 0, 0);background-attachment: scroll;background-clip: border-box;background-image: none;background-origin: padding-box;background-position: 0% 0%;background-repeat: no-repeat;background-size: auto;width: auto;height: auto;border-style: none;border-width: 3px;border-color: rgba(0, 0, 0, 0.4);border-radius: 0px;">首先收集尽可能多的垃圾</strong>(Garbage First)"。因此，G1 并不会等内存耗尽(串行、并行)或者快耗尽(CMS)的时候开始垃圾收集，而是在内部采用了启发式算法，在老年代找出具有高收集收益的分区进行收集。同时 G1 可以根据用户设置的暂停时间目标自动调整年轻代和总堆大小，暂停目标越短年轻代空间越小、总空间就越大； </section></li> <li> <section style="margin-top: 5px;margin-bottom: 5px;color: rgb(20, 20, 20);line-height: 1.8em;letter-spacing: 0em;"> G1 采用内存分区(Region)的思路，将内存划分为一个个相等大小的内存分区，回收时则以分区为单位进行回收，存活的对象复制到另一个空闲分区中。由于都是以相等大小的分区为单位进行操作，因此 G1 天然就是一种压缩方案(局部压缩)； </section></li> <li> <section style="margin-top: 5px;margin-bottom: 5px;color: rgb(20, 20, 20);line-height: 1.8em;letter-spacing: 0em;"> G1 虽然也是分代收集器，但整个内存分区不存在物理上的年轻代与老年代的区别，也不需要完全独立的 survivor(to space)堆做复制准备。G1 只有逻辑上的分代概念，或者说每个分区都可能随 G1 的运行在不同代之间前后切换； </section></li> <li> <section style="margin-top: 5px;margin-bottom: 5px;color: rgb(20, 20, 20);line-height: 1.8em;letter-spacing: 0em;"> G1 的收集都是 STW 的，但年轻代和老年代的收集界限比较模糊，采用了混合(mixed)收集的方式。即每次收集既可能只收集年轻代分区(年轻代收集)，也可能在收集年轻代的同时，包含部分老年代分区(混合收集)，这样即使堆内存很大时，也可以限制收集范围，从而降低停顿。 </section></li> </ul> </section>
