When you allocate the children of an object, if the children need to have similar life time as their parent they should be allocated at the same time so they will stay together on the GC heap.
当你分配对象的子对象时,如果子对象的生存时间和父对象基本相同,他们应该被同时分配以使他们在GC堆中的位置也是相近的。
An application runs until the heap is exhausted of free memory, at which point the GC stops all application code, performs a garbage collect, and then lets the application continue.
应用程序一直运行,直至耗尽堆的可用内存,此时GC停止所有的应用程序代码、执行垃圾收集,然后让应用程序继续运行。
The best way to determine the tenure space size is probably to look at the amount of free heap that exists after each GC in default mode (%free heap x Total heap size).
要确定年老代空间大小,最佳方法可能是在每次采用缺省模式进行 GC 操作之后查看可用堆的量(可用堆百分比乘以总堆大小)。
However, if you look at the rate of GC, you can see that it's higher for the fixed-heap runs.
但是,如果您看一看GC的速率,便可以看出对于固定的堆来说这是较高的速率。

Instead of trying to work out the impact of GC pause times on an application, look at the amount of garbage generated.

By looking at the graph of heap size after GC, you can see the trend of your program's memory usage.
观察gc之后堆大小的图,可以看到程序内存使用的趋势。
At this point, if the heap is consistently less than 40% free or the GC pauses are taking more than 10% of the total run time, you should consider increasing the heap size.
此时,如果堆闲置空间总是低于40%,或者GC暂停高于总运行时间的10%,就应该考虑增加堆大小。
Now the GC runs only every 13 requests, at a slightly higher cost, for a per-request cost of 0.009 seconds.
目前每13个请求GC就会运行一次,代价有些高,每个请求需要耗费0.009秒。
Aside from adding RAM, or at least ensuring that you have sufficient RAM for a 64-bit JVM, you'll also need to spend time tuning the garbage collection (GC) algorithm for the JDK in use.
除了添加RAM(或至少确保拥有64位JVM所需的足够RAM)外,还将需要花时间调整所使用的JDK的垃圾回收(GC)算法。
Use of the remaining time is at the GC's discretion: it can be allotted to the application or it can be used by the GC.
剩余时间的使用由GC决定:可以分配给应用程序也可以由 GC使用。
CLRProfiler is an awesome tool to use to look at your GC heap see what's in there and what's holding objects alive.
CLRProfiler是查看GC堆非常好的工具,可以看到里面有什么对象和哪个对象保持有它的引用,使它成为活的对象。
为什么考虑verboseGC日志?
Once you've defined what your goal is, you can start measuring your application performance, experimenting with different policies, and looking at the verbose GC logs for hints.
在定义了目标之后,就可以开始度量应用程序性能了,使用不同策略进行实验,考虑 verboseGC日志的提示。
What happens at JVM or memory level when we say object is collected by Garbage Collector or GC?
在JVM或记忆水平时,我们说的对象被垃圾收集器收集或GC会发生什么?
And meanwhile, we can expand the heap (by adding new memory segment) at gen 1 if required, do not have to wait until gen 2 GC.
同时,如果需要,可以在第1代收集就扩展堆(增加内存段),而不必等到第2代收集。
