那么，您需要观察您的应用程序，以看出您认为需要变更的特定类与那些类和接口是相关联的。
So, you need to look at your application to see what classes and interfaces are related to a particular class that you think you need to change.
最后，在所有情况中应用程序都观察该事件。
再次声明，不应该将我的结果视为结论性的；最好的测试总是：在每个文件系统上运行您的特定应用程序，以观察它是如何执行的。
Again, my results should not be considered conclusive; the best test is always to try your particular application under each filesystem to see how it performs.
我在RCP应用程序中观察到的另一个问题被我称为映象燃烧，当从磁盘频繁读取一个映象然后丢弃时该问题就会发生。
Another problem I see in RCP applications is what I call image burn, which occurs when an image is frequently read from disk and disposed.
如果事实如此，您可能需要更深层地观察您的应用程序，寻找第一个测试点。
If this is the case, you may need to look deeper into the application to find your first test points.

甚至更好的是，连接路由器提供了另一个安全和监视层；具体说来，它可以很容易地准确报告何时对应用程序进行观察，以及对应用程序观察了多长时间。
Even better, the connection router provides another layer of security and monitoring; in particular, it can easily report on exactly when and how long an application has been viewed.
