This is equivalent to setting noatime on *nix OSes, and is safe, for some value 
of that variable. It does significantly help with access time for processes 
that suffer from disk IO bottlenecks, but is unlikely to be helpful on the 
majority of workstations, unless you have crappy antivirus apps running that 
are constantly scanning your drives.

The biggest help I've found this setting to provide is for file servers that 
have directories with >10k files in them. File access times in those instances 
can nosedive, presenting the end user with very painful explorer browsing.
