Good Deal!  It seems from others that it takes a machine with more processors 
or dual/quad core to benefit from the shell setting.  Mine is such a machine 
as must be yours!  I was amazed at the difference which is why I posted what 
I found.  I don't have or haven't so far found anyway, any drawbacks except 
perhaps that it doesn't seem to work with single core processors.  I'm happy 
with the increase of speed on my machine.  :)
