  Pardon my nitpicking, but you'd only get the speedups that you
mentioned if you were a) running in the cache 100% of the time, and b)
didn't do ANY I/O.  Since no system has cache hits all the time, and
all systems have to do I/O to be useable, there are slowdowns.  Just
because the clock speed is 5.77x the stock GS speed doesn't mean that
the effective speed of the machine is 5.77x that of a stock GS...
