    Description

      In SERVER-29465, we thought it's better to warn the user that Windows is currently in a configuration that causes poor performance. Therefore in the documentation, we can elaborate on this warning and propose recommended configuration.

      Here is the original warning I did in the code, and later Geert thought we should have a dochub link to more detailed documentation. I am putting it here just for a note:

      "The file system cache of this machine is configured to be greater than xx% of
      the total memory.  This can lead to increased memory thrashing and poor
      performance.  We suggest using SetSystemFileCacheSize to limit the amount of
      memory that is used by the file system cache."
      

      More info can be found in the original ticket.
