I was assuming *all* the different odd slowdowns discussed on
the thread were remedied.  (Including the 15 second 
Socket.gethostbyname on localhost.)  Maybe I shouldn't assume
that.

But still, a 15x speedup just from a defrag???  That would still
fit the 'weird' category from my personal experience.  (But then,
I have zero experience with tablet PC's.)


Regards,

Bill

(The 15x figure comes from earlier on the thread where Ron was
comparing various rails tasks on his system compared to Chet's.)
