c# - CLR 4.0 中的垃圾收集改进

Question

最近我正在运行 Andrew Hunter on his blog "The Dangers of the Large Object Heap" 提供的示例针对 .NET 4 编译，我得到以下数字:

With large blocks: 622Mb allocated
With large blocks, frequent garbage collections: 582Mb allocated
Only small blocks: 1803Mb allocated
With large blocks, large blocks not growing: 630Mb allocated

如果针对 .NET 2.0 编译相同的代码，我几乎得到文章中提到的数字:

With large blocks: 21Mb allocated
With large blocks, frequent garbage collections: 26Mb allocated
Only small blocks: 1811Mb allocated
With large blocks, large blocks not growing: 707Mb allocated

如此显着改善的原因是什么？

代码是为 x86 平台编译并在 Windows 7 上运行

Answer 1

CLR 团队的一些急需的工作是改进的原因，但显然仍有改进的空间:
