You would see just that if you test the Lehman with a dataset of semiprimes N with smaller factor > cbrt(N) and parameter doTDivFirst=false ;-) The minimal improvement at bigger sizes would result from the few cases where the "correction loop" is needed, which we put behind the (second) trial division loop.


Anyway, thanks a lot for cross-checking our stuff in C, that is very helpful!
