FIX: Generation 1 garbage collections and generation 2 garbage collections occur much more frequently on computers that have 2 GB or more of physical memory in the .NET Framework 1.1 (893360)


The information in this article applies to:

  • Microsoft .NET Framework 1.1

SYMPTOMS

In the Microsoft .NET Framework 1.1, generation 1 garbage collections and generation 2 garbage collections occur much more frequently on computers that have 4 gigabytes (GB) or more of physical memory than on computers that have 2 GB of physical memory.
