分析：

一共进行了9次YoungGc，用时270ms，回收了843.41M的垃圾
一共进行了5次FullGc，用时250ms，回收了738.4M的垃圾
年轻代一共占用153.56M空间，Eden区136.5M，from和to区都为17M
平均GC暂停时间37.1ms,最大GC暂停时间60ms，最短暂停时间为10ms
一共创建了1.87gb的对象，晋升到老年代的对象有350.86M。垃圾回收第一次到结束一共经历785ms
内存的分配速率为2.38gb/s,对象的晋升速率为446.95M/s

SerialGC汇总分析：

堆内存更大，GC频率更低，内存分配速率更高，对象晋升速率更高，GC暂停时间更长

堆内存更小，GC更频繁，FullGC次数更多，内存分配速率更低，对象晋升速率更慢，GC暂停时间短

年轻代使用 DefNew 垃圾采集器，老年代使用 Tenured 垃圾采集器

分析：

一共进行了23次YoungGc，用时250ms，回收了1.16gb的垃圾
一共进行了8次FullGc，用时310ms，回收了415.92M的垃圾
年轻代一共占用114M空间，Eden区57.5M，from和to区都为56.5M
平均GC暂停时间18.1ms,最大GC暂停时间50ms，最短暂停时间为0ms
一共创建了1.87gb的对象，晋升到老年代的对象有463.99M。垃圾回收第一次到结束一共经历905ms
内存的分配速率为2.07gb/s,对象的晋升速率为512.7M/s

ParallelGC汇总分析：

堆内存更大，GC频率更低，内存分配速率更高，对象晋升速率更高，GC暂停时间更长

堆内存更小，GC更频繁，FullGC次数更多，内存分配速率更低，对象晋升速率更慢，GC暂停时间短

年轻代使用 PSYoungGen 垃圾采集器，老年代使用 ParOldGen 垃圾采集器

分析：

一共进行了18次YoungGc，用时480ms
一共进行了2次FullGc，用时100ms
年轻代一共占用153.56M空间，Eden区136.5M，from和to区都为17M
平均GC暂停时间16.4ms,最大GC暂停时间70ms，最短暂停时间为0ms
一共创建了2.21gb的对象，晋升到老年代的对象有529.12M。垃圾回收第一次到结束一共经历990ms
内存的分配速率为2.38gb/s,对象的晋升速率为534.46M/s

CMSGC汇总分析：

堆内存更大，GC频率更低，内存分配速率更高，对象晋升速率更高，GC暂停时间更长

堆内存更小，GC更频繁，FullGC次数更多，内存分配速率更低，对象晋升速率更慢，GC暂停时间短

年轻代使用 parNew 垃圾采集器，老年代使用 CMS 垃圾采集器

STW时间相比SerialGC以及ParallelGC更短，流程为：初始化标记–标记预清理–并发标记–并发清理–最终标记–最终清理

分析：

一共进行了25次YoungGc，用时110ms
一共进行了29次FullGc，用时190ms
年轻代一共占用14单位空间，survivors占用4单位空间,1单位空间为1024kb大小
平均GC暂停时间3.5ms,最大GC暂停时间20ms，最短暂停时间为0ms
一共创建了2.57gb的对象，晋升到老年代的对象有338.1M。垃圾回收第一次到结束一共经历969ms
内存的分配速率为2.65gb/s,对象的晋升速率为348.92M/s

G1GC汇总分析：

堆内存更大，GC频率更低，内存分配速率更高，对象晋升速率更高，GC暂停时间更长

堆内存更小，GC更频繁，FullGC次数更多，内存分配速率更低，对象晋升速率更慢，GC暂停时间短

将整个堆内存进行分块，每块堆内存所分配的区域都会有改变的情况，不会将分代模型按比例进行堆内存的分配。优化了堆内存的使用效率。GC时间相比其他GC更短，但是GC更频繁。
