If you take into account that MIPS is currently defined as "meaningless indication of processor speed", and BOGO is derived from bogus, you end up with a bogus and meaningless indication of processor speed... Even measuring memory bandwidth is a bogus number on a mainframe, as it depends heavily on the zVM page subsystem, caching and so... Measuring the IO speed can be a little more meaningful, but just a little too.
Want to measure something? Measure throughput. Is a nice number, and a (kind of) real number.
