Potentially, yes, depending on how well your OS handles this, and how often the script is called and so on.
Under linux, with reasonable amounts of RAM, and assuming that the script is called frequently enough for the OS not to re-use the buffers, after the first hit (that maps the file) I'd expect there to be very little disk i/o (if any) when reading that file. --Wez.
