I agree entirely, where details (ie. less factor of 1.5-2 either way) are concerned. However, you and others gained factors of 5 or more that have made the difference that I find impressive. Whether deranged or not.......

This slowup with octave is also a choice. The sort code in octave-forge
uses the mergesort code from python, while matlab uses a quicksort
algorithm. The benchmark above is reversed if partially ordered lists
are used, as for instance often happen in interpolation codes. So octaves
loss in the above benchmark shows more about the choices of the person
writing the benchmark than the octaves relative performance. Benchmarks
are all figments of someones deranged imagination...
