I've seen this asked before, so I ran some tests to try and find the FFT crossover points for LLR. I have narrowed the range of "n" down to 5,000.
Estimated FFT crossover when n= 40,000-45,000 60,000-65,000 85,000-90,000 125,000-130,000 170,000-175,000 210,000-215,000 255,000-260,000 300,000-305,000 340,000-345,000 425,000-430,000 515,000-520,000 600,000-605,000 685,000-690,000 815,000-820,000 980,000-985,000 Hope that helps ![]() The iteration timings and supporting data are hosted here: http://www.15k.org/homeffttime.htm |
