Disable Automatic Update For Better Performance

September 22, 2007 at 3:58 am (General, Tips n Tricks)

If you have NTFS, here’s a Registry hack for increasing its performance. Whenever you view a directory on an NTFS volume, the filesystem updates the date and timestamp to show the last time the directory was accessed. If you have a very large NTFS volume, this continual updating process can slow system performance. To disable automatic updating, run the Registry Editor and go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentContolSet\Control\Filesystem. Look for NtfsDisableLastAccessUpdate. If it’s not present, create it as a DWORD. Set the value to 1.
