The presentation in those "/thres/" pages is a bit strange when it is not operand size cutoff values but, like here, methods. I.e., measured method 3 vs configured method is marked as a major difference. And the average is 0.975... I suppose it would be somewhat interesting to know how close the measured best and measured 2nd best methods are, or how much better the measured best methods is than the configured method. And, when there is asm, the scary performance ratio between C and asm which would suggest that C-to-C comparisons of tight GMP loops might not be terribly relevant. :-) -- Torbjörn Please encrypt, key id 0xC8601622 _______________________________________________ gmp-devel mailing list gmp-devel@gmplib.org https://gmplib.org/mailman/listinfo/gmp-devel
