Performance measurements
In the discussion of performance measurements, it was mentioned that
the VAX-780 was analyzed as a 0.5MIP machine (by Doug Clark). How does
a MIP relate to my compiling a Fortran program or interacting with a
DBMS? And what is a MIP? If we are going to compare machines and
architectures, we need to be more specific. The one thing lacking in
the analysis of machines today is a standard reference point and
definition of work (as opposed to MIP). The measurement should be
the number of functions performed per unit time, where "number of
functions" has some rational base. And note, the "functions" might
be different depending upon the environment of the user.
