performancecounter - .NET CLR 内存 "Bytes in all heaps"远低于 "Gen 0 heap size"

Question

我正在查看 ASP.NET 4 应用程序(工作流服务)的性能计数器

.NET CLR Memory -- # Bytes in all Heaps :    44,420,488
.NET CLR Memory -- Gen 0 heap size :        311,665,568
.NET CLR Memory -- Gen 1 heap size :         17,723,080
.NET CLR Memory -- Gen 2 heap size :         25,956,920
.NET CLR Memory -- Large Object Heap size :     740,488

“# Bytes in all Heaps”计数器的描述

This counter is the sum of four other counters; Gen 0 Heap Size; Gen 1 Heap Size; Gen 2 Heap Size and the Large Object Heap Size. This counter indicates the current memory allocated in bytes on the GC Heaps.

请注意，它说的是“四个其他计数器的总和”，而不仅仅是“在其他四个堆上分配的字节总和”，这是有道理的，因为在第 0 代垃圾收集之后，第 0 代堆中有 0 个字节。

我注意到在我的例子中，#Bytes in all Heaps 正好是 Gen 1 + Gen 2 + Large Object Heap。这是一个错误吗？还是我错过了阅读数字？

Answer 1

根据 this , 所有堆 = Gen 1 + Gen 2 + 大对象堆
(没有第 0 代)
