When you run a 64-bit application in a 64-bit environment, you may notice that the application uses more memory than a similar 32-bit application that is running in a 32-bit environment. This problem may occur when the following conditions are true:
- The application was built by using the Microsoft .NET Framework.
- The application is running under a high memory load.
This problem occurs because the 64-bit version of the .NET Framework garbage collector (GC) performs fewer collections than the 32-bit version of the garbage collector. The range of memory that may be addressed on 64-bit computers differs from the range of memory that may be addressed on 32-bit computers. Therefore, the 64-bit garbage collector runs less frequently than it should.
