Increase SQL server performance by using WIFI(Windows Instant File Initialization)

This is an interesting post I came across by Saleem Hakani. I have not tested it yet.
It promises to reduce the time for
Creating a database
Expand data files for additional growth
Automatic data file growth due to auto-grow settings
Restoring a database, etc.
