Consider the following scenario:

  • You have a computer that is running Windows Vista or Windows Server 2008.
  • Intel I/O Acceleration Technology (I/OAT) is enabled on the computer.
  • You copy files to this computer from another computer that is running a down-level operating system, such as Windows XP and Windows Server 2003.

In this scenario, the file copying is significantly slower than when Intel I/O Acceleration Technology is disabled.
