public class PerformanceMeasurer
For running simplistic performance tests, to measure the number of operations per second.
With a short run, this is "good enough" for eye-balling performance, to spot if it goes
However, good performance measurement involves much more warm up (e.g. to ensure java HotSpot
optimisation have been applied), and running the test for a reasonable length of time.
Longevity tests are also important for to check if object creation is going to kill
performance in the long-term, etc.
