Is it normal for (while working on LM hashes) Cain to be running at ~7.8mil passes/sec while JtR is only able to do about 2mil passes/sec (i am assuming that is what "c/s" measures). The number JtR gives seems to scale according to how many hashes it is working on at a given time, but when only working on two (split LM hash) shouldn't the two give about the same speed? It just seems odd that JtR, which seems to be so popular, would not be slower than a built-in cracker in Cain.
