Thanks again for fixing/enhancing my code! I was able to test it today and it works faster and better than before.
But I still encounter this strange bug. If I just use ./john <myfile>, the speed gets slower over time.
Some numbers:
0g 0:00:00:01 33.54% 1/3 (ETA: 08:32:05) 0g/s 405927p/s 405927c/s 405927C/s
0g 0:00:01:08 69.54% 2/3 (ETA: 08:33:40) 0g/s 43377p/s 535782c/s 535782C/s
0g 0:00:01:39 3/3 0g/s 30441p/s 528406c/s 528406C/s 011087..025246
0g 0:00:05:46 3/3 0g/s 10025p/s 542166c/s 542166C/s
0g 0:00:29:32 3/3 0g/s 3367p/s 543035c/s 543035C/s
0g 0:01:16:24 3/3 0g/s 2320p/s 526810c/s 526810C/s
Is this behaviour normal?
