It is now in git: parallel/doc/boxplot-runtime Don't waste too much time on it, though (It has a lot of dependencies outside Cygwin). I will be surprised if the trend is not the same, and the actual timings (milliseconds) will likely just be a factor off. If it is run on a machine that does other things or which has a dynamic cpu frequency you will see a bigger spread. In my initial tries that spread was so big it completely obscured the trend. /Ole
