"Benchmark it so you can find the bottlenecks."

I believe for _newcomers_, it is much easier and
ultimately better to point them at "better" habits
(insofar as "what is faster"), than tell them to
use benchmarks on their own.

There seems to exist a slight need for these kind of
questions, as they do reappear again and again, probably to
squeeze the max out of ruby's performance.
