PageMania is a tool designed act as a badly behaved application that:

  • Allocates a lot of memory,
  • Reduces it's working set, also called a trimming operation, causing the memory to be flushed out to the page file,
  • Modifies a byte in each memory page to cause page faults and bring it back into it's working set. In most cases, the memory will be retrieved from the standby lists cache so a disk read from the page file will not occur unless memory is in demand. Note that by modifying each page, this will cause the next trimming operation to re-write to the page file again.

This tool is useful for testing other tools that should detect such behavior, or as an example of such a program so that you can know what to look for in non-automated tools like the Task Manager.

 The tool has a simple controls for adjusting the amount of memory, the trimming schedule, and the touching schedule.
