推荐答案

文件计数维护应用程序在一段时间内使用的文档数量，这些文档保存在内存中（不是垃圾回收）。页面上的iframe及其文档也会计入此处。此计数器可能有助于您确定应用程序中的哪些事件可能导致内存泄漏。

The "Document Count" maintains a count of the number of documents used by your application over time, that are held in memory (not garbage collected). Iframes on your page along with their documents are also counted here. This counter may contribute in helping you identify what events in your application may be leading to a memory leak.
