Interesting but did you run the C version on your machine alongside your Ada version? In the text, from what I understand, you are comparing the Ada computation time to the reported OP C performance (17ms) and I fail to understand how the comparison can be valid if performed on different machines? Note: I tried to find the original C code but in vain and from my rapid reading of your blog post you do not mention having run that C code yourself. Thank you, Olivier
