All 3 methods will do blocks of 64 passwords per each crypt-all call (or at least 'up' to 64). A 1.5 to 2x improvement in speed, depending upon the core. The code used was from md5-mmx.S (and stages-*-md5.S). Had to do in blocks of 64, or serious performance hit was seen, due to too much file IO (ftell() calls).
