Well, that's good to know.  The slowdown is due to the POSIX path handling
code.  There's more pain with network activity.  You're welcome to look at 
it though.  PTC! :-)

You might find better performance on the remote drive if you mount it and
use '-E'.  Then again, it may do nothing for your case.
