--- Comment #11 from Michael_S <already5chosen at yahoo dot com> --- (In reply to Michael_S from comment #10) > BTW, the same ideas as in the code above could improve speed of division > operation (on modern 64-bit HW) by factor of 3 (on Intel) or 2 (on AMD). Did it. On Intel it's even better than anticipated. 5x speedup on Haswell and Skylake, 4.5x on Ivy Bridge. Unfortunately, right now I have no connection to my Zen3 test system, so can't measure on it with final variant. But according to preliminary tests the speedup should be slightly better than 2x.
