Speed of shutil.copy vs os.system("copy src dest") in win32

[Tim Golden]

[Russell Warren]

| I just did a comparison of the copying speed of shutil.copy 
| against the
| speed of a direct windows copy using os.system.  I copied a file that
| was 1083 KB.
| 
| I'm very interested to see that the shutil.copy copyfileobj
| implementation of hacking through the file and writing a new one is
| significantly faster... any clue as to why this is?  I figure I'm
| missing something here.

There are a couple of other options as well which
may or may not be faster. I'd meant to time things
before putting this page up but never got round to
it; maybe I'll give it another go:
