the current format for these benchmark scripts is basically samples of number of ops completed over time. so you have two columns - seconds and ops and just draw a graph. Can easily see if scalability is linear, polynomial, or logarithmic, and also how wobbly the line is (between JIT, os disk caching, memory allocation systems, etc it will be!)

Even just running hashes on various input sizes had all sorts of non-linear effects! http://dominictarr.github.io/crypto-bench/

If you just show a single number you don't see that!
