As the example of fixing the heap above showed, an application may sometimes run faster than it did before being tuned but still be marked by an unchanged GC overhead or even longer mean pauses.
正如上文所示的固定堆示例,应用程序可能有时的运行速度比调整前快,但仍然由未改变的GC开销甚至更长的平均暂停时间表示。
An application that has not been touched for a while needs to be upgraded, but the original requirements, design, tests, and sometimes even code can no longer be found.
暂时尚未涉及到的程序需要得到升级,但是有时不能找到原始的需求、设计、测试,甚至代码。
Could be longer than that, sometimes even millions of years.
可能比那更长,甚至几百万年。
