A benchmark measures nothing more than the time needed to execute that
benchmark.

A _good_ benchmark has performance characteristics that are similar to
those of the code you actually intend to run and care about.  Whether
a particular benchmark works well for you is impossible to say without
knowing what you want to measure.

Words like "uniform approach" are meaningless in this context, but I
should mention that I/O is part of the platform, and matters in most
real-world applications.
