The responsiveness is a separate matter, well covered in Mark's replies.

Here my interest is in making sure your operation runs and efficiently 
as it can.

Have you had a chance to explore measuring different executions times as 
you adjust the kBufferSize constant at the top of the script?

Here on my Linux box I found, rather surprisingly, that a buffer as 
small as 128k delivered optimal speeds.  In discussing this with Peter 
Brett it turns out there are memory-mappings provided by the OS that 
seem to play a role there.

It would be very interesting to me to learn what buffer size you find 
optimal on Windows.
