Using MIPS ratings doesn't work out very well for actual performance.
What follows is from comp.windows.x; it's the results for a heavily
scalar floating point intensive program. For scientific applications,
it'll show you the benefits better than raw MIPS ratings.

For simple interactive use, all of these machines are pretty fast &
you should really be looking at things like IO & context switches/second.

Here is the 2nd updated list of xfroot fractal-points/processor_second 
measured on various clients. The number, a count of trips/second
through the 8 line "hopalong" loop in xfroot, is a rough index of scalar 
double-precision floating point uniprocessor speed. New items since the
last posting are marked with ">".
