  There are a number of benchmarks by vendors who report a MIPS figure.
Each will report a different value, and not even the ratio of the
numbers is the same between processors. If I had to pick one I would use
the one from Microway, which comes with math coprocessors. You can
"tune" it to assign weight to one characteristic or another, depending
on your planned usage. I have two profiles around somewhere for general
purpose and math intensive machines.

  Please note: there is no one number which will give you the
"performance" of a machine, not is any one number going to summarize the
relative performance of any two machines. Even the Microway benchmark,
which gives you performance by category, is only an approximate
indicator of DOS performance, and far less accurate for ranking machines
which run multitasking, like Desqview or UNIX.
