    Description

      Problem:
      ./src/mongo/util/processinfo_win32.cpp

      See

      198     bool ProcessInfo::checkNumaEnabled() {
      199         return false;
      200     }

      Appears that this check assumes that there is no NUMA impact for Windows.

      Solution:
      It appears that Windows supports APIs to find this info, see

      http://msdn.microsoft.com/en-us/library/windows/desktop/aa363804(v=vs.85).aspx

      Next Step:
      Confirm if NUMA affects Windows in the same way as Linux (assumption is yes).
