"After all, facts are facts, and although we may quote one to another with a chuckle the words of the Wise Statesman, 'Lies--damned lies--and statistics,' still there are some easy figures the simplest must understand, and the astutest cannot wriggle out of." Leonard Henry Courtney, 1895

tl;dr

Measurement is highly specific -- the time taken for this task, by this program, when compiled with this compiler, with these options, on this machine, with these workloads.

Same program, same machine, same workload -- but very different performance measurements.

Measurement is not prophesy.
