garbage-collection time的意思|示意

There are several costs to card marking - additional space for the card map, additional work to be done on each pointer store, and additional work to be done at garbage collection time.

卡片标记有几项开销——卡片映射所需的额外空间、对每一个指针存储所做的额外工作，以及在垃圾收集时做的额外工作。

These statistics dispense data on the basic JVM features, such as Just-In-Time (JIT) compilation, class loading, memory allocation, and most interestingly, garbage collection.

这些统计信息涉及诸如即时 (JIT) 编译、类加载、内存分配以及最有趣的垃圾收集之类基本的 JVM 特性。

The very last element of each collection element is a element, which records how much time was taken by the garbage collection

每个收集元素的最后一个元素是 元素，该元素记录垃圾收集所用的时间

From the first graph, you see the application had been running for about 100 seconds, so 0.3% of that time had been spent doing garbage collection.

从第一个图形中，您可以看到应用程序运行了大约100秒，所以进行垃圾收集花费了该时间的0.3%。

In any system where work is queuing up, the response time of the system is likely to be dominated by the queueing time, rather than any garbage collection pauses.

如果系统中存在正在排队等候的任务，那么系统的响应时间可能会受到排队时间的控制，而不是垃圾收集停顿时间。

We also do not take for granted the optimization of code by design and we take it with a grain of salt every time somebody tells us how good JVMs are now at optimization and garbage collection.

我们并不认为仅仅通过设计就能得到优化的代码，每当有人说起现在的JVM在优化和垃圾收集方面有多么棒时，我们都对其持保留态度。
