If you don't know, measure. And when you measure, do so
across as many kinds of workloads as you believe will arise.
We measure a lot, which in turn causes us to usually choose
a good approach before measuring. But even still, "usually"
is far from "always".
The JCiP (http://jcip.net/) testing chapter(12) contains some
introductory discussions on performance measurement.
