Hello,
I use Boost.Interprocess on Windows 2003 Server.
I am experiencing performances troubles. I am trying to understand what happens, and arrived on Microsoft web pages.
I seems that on Windows, shared memory is implemented only through mapped files, and that only a portion of the shared memory is physically in the RAM (this limited number of pages is called "working set").
The Windows API provides some functions for this working set :

I would have liked Interprocess wraps the functions GetProcessMemoryInfo() and SetProcessWorkingSetSize(), so that the full shared memory is put in RAM.
But for now, I fear it is impossible to have with Interprocess performances similar to the ones provided by the alternative : data in the process memory.
