Sorry, it\'s a long one, but I\'m just explaining my train of thought as I analyze this. Questions at the end.

I have an understanding of what goes into measuring runni

Answer 1

I had a similar question here.

I much prefer the concept of using a single stopwatch, especially if you are micro benchamrking. Your code is not accounting for the GC which can affect performance.

I think forcing a GC collection is pretty important prior to running test runs, also I am not sure what the point is of a 100 warmup run.
