Remember that processor speed is only one of many items determining speed.
I/O is extremely significant and this has not increased at the same rate as
processors. Other aspects such as memory cache and new hardware (firmware?)
instructions (if they are taken advantage of by the code) also play a part.
If speed is important to you for a particular project your best bet is to
set up typical code representing what you will be doing and then run
benchmarks.

What I meant to say was that for equal intervals of time
(each X number of years), the speed of computers increases
exponentially. So that it is not uncommon have the need to
make MW projects that run on computers that are
1x 2x 4x 8x 16x

That is why I think a slider that controls the speed of
projects that we want to run on such a variety of
hardware needs to have something exponential in it, to.
