The Analysis of Software Memory Leak Defect and Research of Test Approach

When tuning for generational garbage collection, the simplest approach is to treat the nursery space as a new Java heap area, in addition to the Java heap area used in the non-generational case.

调优分代垃圾收集时，最简单的方法是将托儿所空间视为非分代垃圾收集使用的Java堆区域之外的新Java堆区域。

If you are running on a32-bit JVM ( not recommended for large object processing) you can maximise the space available to process large BOs by not using generational garbage collection.

如果您在32位JVM（不建议用于大型对象处理）上运行，那么您可以通过不使用分代垃圾收集来最大化可用于处理大BO的空间。

The algorithm improved the division of generation and reference tracking of the generational garbage collection algorithm for reducing time and memory requirements, and made it suitable for resource-constrained embedded environments.

该算法对分代回收算法中代的划分方式，引用跟踪等方面进行改进，以降低对运行时间和内存空间的需求，从而使其适用于资源有限的嵌入式环境。

Generational garbage collection turns out to be very effective, although it introduces several additional bookkeeping requirements at runtime.

分代收集证明是非常高效的，尽管在运行时它需要更多的簿记。

One of the advantages of generational collection is that it can make garbage collection pauses shorter by not collecting all generations at once.

分代收集的一个优点是它不同时收集所有的代，因此可以使垃圾收集暂停更短。

Optthruput: ( default in V7) Performs the mark and sweep operations during garbage collection when the application is paused to maximize application throughput.

optthruput：（默认）当应用程序暂停时，在垃圾收集过程中执行标记和清扫操作，以便最大限度提高应用程序吞吐量。

The true challenge of this project was to take the existing reference counting system and move it over to the mark and sweep model in the existing code base without breaking old content.

这个项目真正的挑战在于替换：必须在已有代码基础上，把引用计数系统整个换成标记-扫描系统，而完全不破坏过去的内容。

The time spent in GC pauses for the mark and sweep phases of a garbage collection are based on the number of live objects on the heap.

用于垃圾收集的标记和清扫阶段的GC暂停时间基于堆上的活动对象的数量。

Optavgpause: Performs the mark and sweep concurrently while the application is running to minimize pause times; this provides the best application response times.

optavgpause：在应用程序运行时并发执行标记和清扫操作，以便最大限度缩短暂停时间；这将提供最理想的应用程序响应时间。

As you increase the heap size on a consistent workload, the mark and sweep phases will continue to take approximately the same length of time.

当您增加统一工作负载上的堆大小时，标记和清扫阶段将继续花费大致相同的时间完成操作。

The same mark-sweep-compact collector is used, but much of the mark and sweep phases can be done as the application runs.

这种策略也使用“标记-清扫-压缩（mark-sweep-compact）”收集器，但大部分标记和清扫工作可以在应用程序运行时执行。

In this type of GC, only the mark and sweep phases of GC are run.

在这类GC内，只运行GC的mark和sweep阶段。

A GC pause usually consists of two distinct phases: the mark and sweep phases.

GC暂停通常包括两个独立阶段：标记阶段和清理阶段。

Since WinRT is built on top of COM you have the same problems with the dichotomy between reference counting and mark-and-sweep garbage collectors.

由于WinRT是基于COM构建的，所以你同样会有引用计数和mark-and-sweep垃圾回收器之间无法融合的问题。

Inter-core coordination, that is, memory barrier semantics, clearly has its overhead as evidenced by the performance of the benchmark when running on my system with one of the cores turned off.

不同核之间的协调，比如存储关卡语义，通过关掉一个核运行的测试结果看，很明显会带来系统开销。

The memory barrier is a signal that tells the CPU that it must coordinate with all the other CPUs in order to fetch the most up to date value.

存储关卡像一个信号，它通知CPU此时必须和其他所有的CPU进行协调，以此获得最新的数值。

Mutexes will insert a" memory barrier," which ensures that the writes to main memory occur in the order the threads lock the mutex.

互斥对象将插入一道“内存关卡”，由它来确保对主存的写入按照线程锁定互斥对象的顺序进行。
