39400: Registry Tweaks For Improving Performance On Win 2003 Servers

There are two registry tweaks specific to Windows 2003 servers which will improve performance under certain conditions. These changes are recommended for our customers who have:

  • A large number of files shared out.
  • Folders containing a lot of items (browsing large folders).
  • A lot of users or if the server is under heavy load.
  • Background processes that monitor the file system for changes such as Windows Search.


  • Windows Vista/2008/7 already sets these values as the default so there is no need to make changes.
  • A reboot is required for new settings to take effect.
