Have a look at 7eaf415. What I do is process (and log) the rules once, putting the accepted rules in a list. In the hot loop I just walk that list. This is 8x faster so was very welcome. Still, without rules I get 35M c/s and with rules I only get about 8M c/s. I can't see how to make it faster now? Speed measured using: ../run/john -stdout --prince -v:1 -prog=10 [-rules] magnum
