> I was expecting a little variation in execution time for each comparison, but what I wasn't expecting was the bimodal nature of the results. For each function, there were two distinct groups of execution times. These peaks existed for all the function types at consistent relative spacings, which suggests that certain vector comparisons took longer than others no matter which distance function was being used Surely pre- and post- JIT?
