:) Reminds me of a story told by Fred Brooks Jr. in the Mythical Man 
Month.  I think it was the S/360.  After most of the work had been done, 
the engineers set about optimising various algorithms that the system 
used - to make it faster and more efficient.

They found a particular loop that was really badly implemented, and 
optimised it so that it ran 80% faster!

You can imagine their surprise when it had no effect whatsoever on the 
speed of the system as a whole.

They had optimised the system idle loop.
